-imidazole-4,5-dicarboxylato]In the title complex, [Co(C5HN2O4)(C10H8N2)]n, the asymmetric unit contains two crystallographically independent monomer units with similar geometry. The CoII cations are coordinated octahedrally by two carboxylate O atoms and by four N atoms, two of which belong to the 2,2-bipyridine ligand and two to different imidazole rings. The connectivity between the metal cations and the imidazole-4,5-carboxylate units gives rise to one-dimensional zigzag chains parallel to [010].
All chemicals were purchased from Acros Co. Ltd. Compound (I) was obtained under hydrothermal conditions by reaction of cobalt sulfate (0.5 mmol), imidazole-4,5-dicarboxylic acid (0.5 mmol), 2,2-bipyridine (0.5 mmol) and KOH (1 mmol) in 20 ml distilled water. The mixture was heated in a 30 ml autoclave at 453 K for 3 d. Red crystals were obtained in a yield of approximately 25%. Analysis calculated for C15H9N4CoO4: C 48.96, H 2.47, N 15.23, Co 15.95%wt; found: C 48.98, H 2.51, N 15.27, Co 16.08%wt.
All H atoms were positioned geometrically and refined as riding atoms with C—H= 0.93Å and Uiso(H) = 1.2Ueq(C).

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. |

Hybrid organic-inorganic materials are important materials because of their application in catalysis, as optical materials, membranes, and in sorption (Church & Halvorson, 1959; Chung et al., 1971), as well as in biological systems (Okabe & Oya, 2000; Serre et al., 2005; Pocker & Fong, 1980; Scapin et al., 1997). Herein, we report a new compound, catena-poly[(2,2-bipyridine)(imidazole-4,5-dicarboxylate)cobalt(II)], (I).
In the structure of compound (I), the asymmetric unit contains two crystallographically independent molecules with nearly the same geometry. As shown in Fig. 1, the CoII cations exhibit a distorted octahedral coordination sphere, made up of two carboxylate oxygen atoms and four nitrogen atoms, two of which belong to the 2,2-bipyridine ligand and the other two to the imidazole ring. The Co—O and Co—N bond lengths are in the usual ranges with 2.1569 (18) to 2.2562 (19) and 2.077 (2) to 2.271 (2) Å, respectively. The two carboxylate groups of the imidazole-4,5-dicarboxylate ligand coordinate in a monodentate fashion to the CoII ions, whereby the connectivity between the cations and the ligands gives rise to one-dimensional zigzag chains along [010] (Fig. 2). The 2,2-bipyridine ligands are situated in the space between the chains.
