The title compound, (C10H9N2)[Cr(C7H3NO4)2]·4H2O or (4,4′-bipyH)[Cr(pydc)2]·4H2O (where 4,4′-bipy is 4,4′-bipyridine and pydcH2 is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of chromium(III) chloride hexa­hydrate with pyridine-2,6-dicarboxylic acid and 4,4′-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic complex, [Cr(pydc)2], protonated 4,4′-bipyridine as a counter-ion, (4,4′-bipyH)+, and four uncoordinated water mol­ecules. The anion is a six-coordinate complex with a distorted octa­hedral geometry around the CrIII atom, formed by two tridentate pyridine-2,6-dicarboxyl­ate, pydc2−, groups. Inter­molecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, and C—O⋯π stacking inter­actions (with distances of 3.3390 (13) and 3.4575 (13) Å) connect the various components into a supra­molecular structure.

The molecular structure of the title compound is shown in Fig. 1. Hydrogen bond lengths are given in Table 1. According to the crystal structure, the title compound is composed of an anionic complex, [Cr(pydc)2]-, protonated 4,4'-bipyridine as a counter ion, (4,4'-bipyH)+, and four uncoordinated water molecules.

The CrIII atom is six-coordinated by two pyridine-2,6-dicarboxylate, pydc2-, groups which act as a tridentate ligand through two O and one N atoms. The O8—Cr1—O1—C1 and O8—Cr1—O4—C7 torsion angles (-89.13 (9)° and 95.98 (9)°, repectively) show that these two pydc2- groups are perpendicular. So the anionic complex has distorted octahedral geometry around CrIII atom. For balancing the anionic complex, a protonated 4,4'-bipyridinium, (4,4'-bipyH)+, exists.

In the crystal structure of (4,4'-bipyH)[Cr(pydc)2].4H2O complex, the spaces between two layers of [Cr(pydc)2]- anions are filled with (4,4'-bipyH)+ cations and water molecules (Fig. 2). The angle between two planes passing through aromatic rings of (4,4'-bipyH)+ is 51.45 (6)°, indicating the flexibility of the C—C bond between two rings.

A considerable feature of title compound is the presence of C—O···π stacking interactions between C1—O2 and C7—O3 and Cg1 [Cg1 is centroid for N1/C2—C6 ring] with O···π distances of 3.3390 (13) Å (1 - x, 1 - y, -z) and 3.4575 (13) Å (-x, 1 - y, -z), respectively (Fig. 3).

Intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds with D···A ranging from 2.6736 (14) Å to 3.4235 (18) Å (Table 1), ion pairing and C—O···π stacking interactions seem to be effective in the stabilization of the crystal structure, resulting in the formation of an interesting supramolecular structure.

Experimental top

A solution of CrCl3.6H2O (133 mg, 0.5 mmol) in water (5 ml) was added to an aqueous solution of pyridine-2,6-dicarboxylic acid (167 mg, 1 mmol) and 4,4'-bipyridine (312 mg, 2 mmol) in water (10 ml) in a 1:2:4 molar ratio and refluxed for an hour. Purple crystals of the title compound were obtained after allowing the mixture to stand for two weeks at room temperature.

Refinement top

The H-atoms were included in calculated positions and treated as riding atoms, with the exception of H atoms on the water molecules. The latter were located in a low theta Fourier map and refined by a constrained rigid type geometry, where O—H = 0.85 Å and C—H = 0.95 Å with Uiso(H) = 1.2Ueq (parent O or C-atom).

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.
