The combination of the active pharmaceutical ingredients furosemide [4-chloro-2-(furan-2-ylmethylamino)-5-sulfamoylbenzoic acid] and pentoxifylline [3,7-dimethyl-1-(5-oxohexyl)-3,7-dihydro-1H-purine-2,6-dione] produces a 1:1 cocrystal, C12H11ClN2O5S·C13H18N4O3, (I), a 1:1 cocrystal hydrate, C12H11ClN2O5S·C13H18N4O3·H2O, (II), and a 1:1 cocrystal acetone solvate, C12H11ClN2O5S·C13H18N4O3·C2H6O, (III). These structures exhibit the presence of a rarely encountered synthon with the graph set R22(7). All potential hydrogen-bond donors of furosemide participate in hydrogen-bond formation in (I)–(III). However, only two hydrogen-bond acceptors of furosemide are active in (I) and (II), and only one is active in (III). Four hydrogen-bond acceptors of pentoxifylline are active in (II), three in (I) and two in (III). These observations are in good agreement with the calculated packing indexes of 69.5, 69.6 and 68.8% for (II), (I) and (III), respectively.

Furosemide was obtained by recrystallization of `Furosemīds Olainfarm'
tablets, produced by JSC Olainfarm, Latvia. Pentoxifylline was obtained by
recrystallization of `Trental' tablets, produced by Sanofi–Aventis
Deutschland GmbH. Crystals suitable for single-crystal X-ray analysis were
grown at room temperature by slow evaporation from methanol for (I), rectified
ethanol for (II) and acetone for (III). The molar ratio of furosemide and
pentoxifylline in each case was 1:1.
All H atoms were positioned geometrically, with C—H = 0.93 or 0.97 Å, and
refined as riding on their parent atoms, with Uiso(H) =
1.5Ueq(C) for methyl groups and 1.2Ueq(C) otherwise.

Special details top
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 for ALL reflections except those flagged by the user
for potential systematic errors. 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. |

Special details top
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. |

Special details top
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. |

As an alternative to pharmaceutical fixed-dosage combinations, it is possible to assemble different active pharmaceutical ingredients in one crystal lattice by cocrystallization. In this work, we present cocrystals (I)–(III) of the cardiovascular drugs furosemide and pentoxifylline. The former is an important loop diuretic (Agyralides et al., 2004) and the latter is indicated to treat intermittent claudication resulting from obstructed arteries in the limbs (Nieder et al., 2005).
The bond lengths and angles in the molecules of (I)–(III) are close to standard values (Allen et al. 1987).
Besides the pharmaceutical importance of the cocrystals obtained, it was interesting to observe the influence of the crystal environment on the molecular conformations of the furosemide and pentoxifylline molecules by comparison of the corresponding conformations in single- and multicomponent crystal structures. There are two polymorphic forms of pentoxifylline reported in the literature, namely triclinic (Pavelčík et al., 1989) and monoclinic (Stepanovs & Mishnev, 2011), and three polymorphic forms of furosemide have been reported by Lamotte et al. (1978) and Babu et al. (2010). One can see that in (I)–(III), the pentoxifylline molecule adopts a conformation close to that in the monoclinic form, while the torsion angles of furosemide vary in a wide range (Table 1). Apparently, due to its flexibility, furosemide can be considered as a useful coformer, capable of adopting the conformation required for a particular crystalline environment and content.
For convenience, we denote the purine bicycle of the pentoxifylline molecule by A+B and the benzene and furan rings by C and D, respectively. The dihedral angle between the A+B and C mean planes is 3.8° in (I), 7.4° in (II) and 22.9° in (III). The C/D angle is close to 85° in all furosemide polymorphs, but in cocrystals (I)–(III) its value lies between 58.8 and 79.8°.
π–π stacking interactions are present in (I)–(III). The centroid–centroid distance between furosemide ring C and the five-membered ring of the pentoxifylline purine system A+B is 3.65 Å in (I) and the centroid–centroid distances between purine systems is 3.51 Å in (III). No π–π stacking interactions were observed in the (II).
In (I)–(III), three hydrogen-bond donors of furosemide participate in the formation of an intermolecular hydrogen bond. Four furosemide hydrogen-bond acceptors are active in (II) and only three are active in (I) and (III). For pentoxifylline, the highest number of active hydrogen-bond acceptors (four) is observed in (II), three hydrogen-bond acceptors are active in (I) and two in (III). There is one hydrogen-bond donor in pentoxifylline in (I)–(III). The hydrogen-bonding geometry in (I)–(III) is presented in Tables 2, 3 and 4, respectively. In all three crystal structures, an intramolecular N15—H···O13 hydrogen bond is present in the furosemide molecule. Atom N2 participates as a hydrogen-bond donor in two hydrogen bonds, where atoms O35 and O36 are acceptors. An N2—H···O36 hydrogen bond is present in (I) but absent in (II) and (III). All three structures exhibit the rarely encountered R22(7) graph-set motif (Bernstein et al., 1995).
In (II), the water molecules connect the pentoxifylline molecules into infinite chains along the crystallographic b axis by strong O—H···O hydrogen bonds. In (III), the acetone solvent molecule participates in N—H···O hydrogen bonding with the amino group of furosemide.
It should be noted that the packing index (the percentage of filled space) (Spek, 2009) has the largest value of 69.6% for (II) and corresponds to the maximum number of realized hydrogen bonds; the packing index is 69.5% for (I) and 68.8% for (III)
