Single crystals of (Ia), (Ic) and (Id) were obtained by cocrystallization of commercially available nitrofurantoin with 1-(4-fluorophenyl)biguanide hydrochloride (Table 8). Solvent evaporation experiments with mixtures of nitrofurantoin and 2,6-diacetaminopyridine yielded (Ib), (Ie) and the cocrystal, (I.II) (Table 9).
For the preparation of compound (II), 2,6-diaminopyridine (5 g, 0.046 mol) was added to a solution of acetic acid anhydride (10.4 ml, 0.055 mol) in 1,4-dioxane (100 ml) under a nitrogen atmosphere. The reaction mixture was heated at reflux for 24 h. After cooling to room temperature, the solvent was removed using a rotary evaporator. Unreacted 2,6-diaminopyridine and acetic acid anhydride were rinsed away with water. 11.5 mg of 2,6-diacetaminopyridine dissolved in dimethylformamide (200 µl) at 323 K yielded (II).
Crystals (Ia), (Id) and (I.II) show Rint-values higher than 0.100: 0.176 (Ia), 0.147 (Id) and 0.138 (I.II), although the data sets were collected with high redundancy: 6.52 (Ia), 6.32 (Id) and 8.98 (I.II). (Ia) and (Id) did not diffract very strongly [Rσ values: 0.106 (Ia) and 0.099 (Id)], but there is no obvious reason for (I.II). However, all other important quality criteria are satisfied.
The H atoms, except those bonded to disordered solvent atoms, were initially located by difference Fourier synthesis. Subsequently, H atoms bonded to C atoms were refined using a riding model, with methyl C—H = 0.98 Å, secondary C—H = 0.99 Å and aromatic C—H = 0.95 Å and with Uiso(H) = 1.5Ueq(C) for methyl H or 1.2Ueq(C) for secondary and aromatic H. H atoms bonded to N atoms were refined isotropically.
In (Ib), the O atom of the dimethyl sulfoxide lies on a twofold axis so that the S atom is disordered. In (Ic), (Id) and (Ie), all solvent atoms except O are disordered over two positions, but the disordered methyl C atoms coincide pairwise thus forming a rectangular arrangement together with the O atom. The site-occupation factors for the major occupied orientations are 0.646 (7) in (Ic), 0.53 (1) in (Id), 0.926 (5) and 0.882 (6) in (Ie). For the minor occupied orientations of both solvent molecules in (Ie), similarity restraints were applied and the carbonyl C and the N atoms were refined isotropically.
In (II), the methyl groups of 2,6-diacetaminopyridine are rotationally disordered over two positions, with site-occupation factors of 0.58 (5) and 0.66 (2) for the major occupied orientations.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Nitrofurantoin is an antibacterial drug used for the treatment of urinary tract infections. It is reduced by bacterial flavoproteins to reactive intermediates, which inhibit the processes of protein synthesis, aerobic energy metabolism as well as DNA, RNA and cell wall synthesis (Cadwallader & Jun, 1976). The resistance of E. coli to other antibiotics has led to an increased interest in this drug in spite of its severe side effects (Cunha, 2006). In many countries, it is illegally applied as an animal food additive, which can further be passed to humans through the food chain and cause plenty of diseases. Since the present quantification of nitrofurantoin is time-consuming and costly, diaminopyridine derivatives are developed as artificial receptors for its recognition. The drug–receptor complex is characterized by one N—H···N and two N—H···O hydrogen bonds and has been examined by NMR spectroscopy (Athikomrattanakul et al., 2009).
A study of the Cambridge Structural Database (CSD, Version 5.31 of November 2009, plus three updates; Allen, 2002) revealed that similar hydrogen-bond patterns are observed in cocrystals of 2,6-diaminopyridine derivatives and six-membered ring compounds with complementary functional groups [CSD refcodes: DOPCUG (Feibush et al., 1986), FODTIB (Hamilton & Van Engen, 1987), MAWPUW (Li et al., 2005), VABVID and VABVOJ (Muehldorf et al., 1988), XESSAQ (Spange et al., 2006)]. Since no such cocrystal with five-membered ring compounds has been reported, we cocrystallized nitrofurantoin and 2,6-diacetaminopyridine. In addition to the desired cocrystal, (I.II), five pseudopolymorphs of nitrofurantoin crystallized during the various cocrystallization experiments: a dimethyl sulfoxide solvate, (Ia), a dimethyl sulfoxide hemisolvate, (Ib), two dimethylacetamide solvates, (Ic) and (Id), and a dimethylacetamide disolvate, (Ie). Furthermore, a 2,6-diacetaminopyridine dimethylformamide solvate, (II), was obtained.
Compounds (Ia) and (Ib) formed during cocrystallization attempts from dimethyl sulfoxide (DMSO). (Ia) crystallized in the monoclinic space group P21/c with one nitrofurantoin and one DMSO molecule in the asymmetric unit. Both molecules are linked by an N—H···O hydrogen bond (Fig. 1). C—H···O interactions between nitrofurantoin molecules lead to ribbons running along the a axis, which are further stabilized by van der Waals interactions to a herringbone pattern (Fig. 2). Compound (Ib) crystallized in the monoclinic space group C2/c as a hemisolvate. The DMSO molecule lies on a twofold axis with the S atom disordered over two positions (Fig. 3). The packing of (Ib) shows zigzag chains of C—H···O-bonded nitrofurantoin molecules running along the a axis (Fig. 4).
Crystallization attempts from dimethylacetamide (DMAC) yielded another three nitrofurantoin solvates, (Ic), (Id) and (Ie). (Ic) and (Id) crystallized with one nitrofurantoin and one DMAC molecule in the asymmetric unit (Figs. 5 and 6). In both structures, the DMAC molecule is disordered over two sites with all non-hydrogen atoms of these two sites in a common plane (r.m.s. deviation = 0.024 Å). (Ic) crystallized in the triclinic space group P1, (Id) in the monoclinic space group P21/c. A similar hydrogen-bond pattern is observed: the nitrofurantoin molecules are linked to each other by C—H···O and to the solvent molecules by N—H···O interactions. However, the packing motifs of the two polymorphs are quite different. Nitrofurantoin and solvent molecules form ribbons parallel to the (0 2 3) plane in (Ic) and zigzag chains running along the b axis in (Id) (Figs. 7 and 8). In structure (Ie), which crystallized in the monoclinic space group P21/c, there are two independent solvent molecules (Fig. 9). Again, each DMAC molecule is disordered over two sites with a planar arrangement of all non-hydrogen atoms (r.m.s. deviation = 0.024 and 0.038 Å, respectively). The nitrofurantoin molecules are linked to one of these by an N—H···O and to the other one by a C—H···O hydrogen bond. The packing shows layers parallel to the (5 0 2) plane (Fig. 10).
In the five pseudopolymorphs, (Ia)–(Ie), the configuration of nitrofurantoin with respect to the C7═N6 double bond is E with C7–H pointing towards the methylene group of the imidazolidinedione ring. The dihedral angle between the planes through the two rings varies from 5.9 (1) to 12.4 (1)°. Since also the nitro group is rotated by less than 10° with respect to the furan ring, the molecules are almost planar (Table 10). Due to the rotatable C7—C8 bond, nitrofurantoin can adopt two forms: an antiperiplanar conformation between N6 and the furan O9 atom [as in (Ib)] and a synperiplanar conformation (observed in the other four pseudopolymorphs). According to an ab initio energy calculation with geometry optimization [program Gaussian; basis set: RHF/6–31+G(d); Frisch et al., 2004], the synperiplanar conformation is by 11.8 kJ mol-1 less stable than the antiperiplanar one. Since high-energy conformers are rarely observed in crystal structures (Weng et al., 2008), we examined all five entries of nitrofurantoin in the CSD [refcodes: HAXBUD, HAXBUD01 (Pienaar et al., 1993a), LABJON (Bertolasi et al., 1993), LABJON01 and LABJON02 (Pienaar et al., 1993b)], which confirmed that apparently the higher-energy conformer is preferred in the solid state. A detailed analysis with our force-field program MOMO (Wagner et al., 2009), which also clearly favoured the antiperiplanar conformation, yielded that the energy difference is caused by electrostatic interactions. A closer examination of the molecular charge distribution calculated by Gaussian shows that the positive and negative charges are equally distributed in the antiperiplanar conformation, while in the synperiplanar one the molecule has positive and negative sides (Fig. 11). This may promote a more compact crystal packing, which would explain why the less stable conformer is favoured in the solid phase.
During the preparation of the nitrofurantoin receptor 2,6-diacetaminopyridine it crystallized as a dimethylformamide (DMF) solvate, (II), in the monoclinic space group P21/c. Both methyl groups of the 2,6-diacetaminopyridine molecule show rotational disorder and are antiperiplanar to the pyridine ring atoms. Thus the two N—H bonds are directed to the same side as the pyridine N atom (Fig. 12). The 2,6-diacetaminopyridine and the DMF molecule are connected by an N—H···O hydrogen bond from one amide group. These entities form zigzag chains along the c axis stabilized by further N—H···O bonds between the other amide groups (Fig. 13). Similar conformations are observed in the crystal structures of solvent-free 2,6-diacetaminopyridine [refcodes: DOPDAN (Feibush et al., 1986) and DOPDAN01 (Mahapatra et al., 2009)].
The desired complex (I.II) crystallized in the monoclinic space group P21/n, with nitrofurantoin and 2,6-diacetaminopyridine connected by one N—H···N and two N—H···O bonds (Fig. 14). As in (Ib), the nitrofurantoin molecule adopts the antiperiplanar conformation as well as the usual E configuration of the C═N double bond. The nitro group and the furan ring are coplanar and the planes through the furan and the imidazolidinedione moiety form a dihedral angle of 9.0 (1)°. Similar to (II), the carbonyl O atoms of the 2,6-diacetaminopyridine molecule point away from the pyridine N atom. One of the amide groups is coplanar with the pyridine ring, while the other one encloses a dihedral angle of 16.7 (1)° with it. The crystal packing shows layers parallel to the (1 0 3) plane, which are stabilized by C—H···O interactions between both components (Fig. 15).
Nitrofurantoin forms an N—H···O and a C—H···O hydrogen bond in all (pseudo)polymorphs. Interestingly, the N—H···O bond connects two nitrofurantoin molecules only in the solvent-free forms (LABJON, LABJON01 and LABJON02); in the solvates [(Ia)–(Ie), HAXBUD, HAXBUD01], it is formed to the solvent molecule. The C—H···O interaction (always with participation of the C—H bond of the hydrazone moiety N—N═C—H) usually connects two nitrofurantoin molecules and thus plays a significant role for the crystal packing, also for that of the complex (I.II). Even though its molecular structure in solvent-free forms and the dimethylformamide solvate (II) is very similar, 2,6-diacetaminopyridine shows some conformational flexibility. The dihedral angle between the planes through the amide groups and the pyridine ring varies from 2.8 to 33.4° depending on the hydrogen-bond interactions. In the cocrystal (I.II), the hydrogen-bonded complexes are further linked by C—H···O interactions to the amide. As a result of that, the 2,6-diacetaminopyridine molecule is not planar. Altogether, since no crystal structure of a complex between nitrofurantoin and a 2,6-diaminopyridine derivative has yet been published, the cocrystal (I.II) confirms the NMR study (Athikomrattanakul et al., 2009) of this drug–receptor complex.
