2,9-Dimethyl-1,10-phenanthrolin-1-ium 2,4,5-tri­carb­oxy­benzoate monohydrate

K.-L. Zhong

Abstract top

In the preparation of the title hydrated salt, C14H13N2+·C10H5O8-·H2O, a proton has been transfered to the 2,9-dimethyl-1,10-phenanthrolinium cation, forming a 2,4,5-tri­carb­oxy­benzoate anion. In the anion, the mean planes of the protonated carboxyl­ate groups form dihedral angles of 11.0 (5), 4.4 (5) and 80.3 (4)° with the benzene ring to which they are attached. The mean plane of the deprotonated carboxyl­ate group forms a dihedral angle of 10.6 (5)° with the benzene ring. In the crystal, the anions are involved in carb­oxy­lic acid O-H...Ocarbox­yl hydrogen bonds, generating a two-dimensional network parallel to (001) containing R44(28) and R44(32) motifs. The 2,9-dimethyl-1,10-phenanthrolinium cations and water mol­ecules reside between the anion layers and are connected to the anions via N-H...Owater and Owater-H...Ocarbox­yl hydrogen bonds. An intra­molecular O-H...O hydrogen bond is also observed in the anion.

Comment top

It is well established that hydrogen bonds play vital roles in molecular recognition and supramolecular chemistry (Batten & Robson 1998; Juan et al., 2002; Qiu et al., 2008), owing to their moderately directional intermolecular interaction which can effectively control short-range packing. 1,2,4,5-Benzenetetracarboxylic acid (Li et al., 2003; Oscar et al., 2008) has been widely applied in constructing interesting supramolecular networks because it acts not only as hydrogen bond acceptor but also as a hydrogen bond donor, depending upon the number of deprotonated carboxylate groups. Some proton-transfer compounds of 1,2,4,5-benzenetetracarboxylic acid with nitrogen Lewis bases, such as guanidinium pyromellitate trihydrate monoperhydrate (Adams & Ramdas, 1978), 2,2'-bipyridinium hemi[1,2,4,5- benzenetetracarboxylate(2-)] hemi(1,2,4,5-benzenetetracarboxylic acid) (Mrvos-Sermek et al., 1996), guanidinuium 2,9-dimethyl-1,10-phenanthrolinium trihydrogen-1,2,3,4-teracarboxybenzoate monohydrate (Sun et al.,, 2002a), imidazolium trihydrogen-1,2,4,5-benzenetetracarboxylate (Sun et al., 2002b), 6,21-diaza-3,9,18,24-tetraazoniatricyclo[22.2.2.211,14] triaconta-11,13,24,26 (1),27,29-hexaene benzene-1,2,4,5-tetracarboxylate(4-) hexahydrate (Zhu et al., 2002) and ethylenediammonium bis(trihydrogen-1,2,4,5-benzenetetracarboxylate) dehydrate (Li et al., 2006) have been synthesized and reported. The title compound (I) was obtained unintentionally during an attempt to synthesize mixed-ligand transition metal complexes with 1,2,4,5-benzenetetracarboxylic acid and 2,9-dimethyl-1,10-phenanthroline ligands via a solvo thermal reaction. Its crystal structure is reported herein.

The asymmetric unit of (I) (Fig. 1) is comprised of a 2,9-dimethyl-1,10-phenanthrolinium cation, a trihydrogen-1,2,4,5-benzenetetracarboxylate anion and a solvent water molecule. The proton transfer from a carboxyl group to the ring N atom (N1) of the 2,9-dimethyl-1,10-phenanthroline is manifested in an increased internal angle [C1—N1—C12 = 123.7 (3)°] of the pyridine ring, compared with that for atom N2 of the pyridine ring [C10—N2—C11 = 117.8 (3)°]. The protonation diminishes the steric effect of the lone pair of electrons and is responsible for the slightly increased C1—N1—C12 angle. In the anion, the mean-planes of the protonated carboxylate groups form didedral angles of 11.0 (5) ° for C34/O1/O2, 4.4 (5)° for C36/O5/O6 and 80.3 (4) ° for C37/O7/O8, with the benzene ring to which they are attached. The mean-plane of the deprotonated carboxylate group C35/O4/O4 forms a dihedral angle of 10.6 (5) ° with the benzene ring. Symmetry-related trihydrogen-1,2,4,5-benzenetetracarboxylate anions interact via O5—H5···O1i and O8—H8···O3ii hydrogen bonds, forming a two-dimensional supramolecular layer parallel to (001), which involves R44(28) and R44(32) motifs (Bernstein et al., 1995) (Fig. 2 & Table 1). The 2,9-dimethyl-1,10-phenanthrolinium cations are linked to the water molecules (O1W) through N1—H1A···O1Wiii hydrogen bonds and reside between the two-dimensional supramolecular layers and are connected to the layers via O1W—H1WA···O4ii and O1W—H1WB···O7iv hydrogen bonds (Fig. 3 & Table 1).

Experimental top

2,9-Dimethyl-1,10-phenanthroline (0.1 mmol), 1,2,4,5-benzenetetracarboxylic acid (0.1 mmol), ZnSO4·7H2O (0.1 mmol) and 2.0 ml water were mixed and placed in a thick Pyrex tube, which was sealed and heated to 383 K for 72 h, whereupon colorless block-shaped crystals of (I) were obtained.

Refinement top

The H atoms bonded to C atoms were were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93, 0.96 Å; Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl)). The H atoms bound to N and O were placed in calculated positions with N—H = 0.86 Å, O—H = 0.82 Å and refined with Uiso(H) = 1.2Ueq(N) and Uiso(H) = 1.5Ueq(O). The precision of the structure is slightly lower than normal as reflected in the R-factors. We attempted to use serveral crystals but the crystal used to collect the data herein was the best quality avaiable.

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.
