Aqua-[2,2'-(propane-1,3-di-yl)bis-(5-car-boxy-1H-imidazole-4-carboxyl-ato)-κ(4)N(3),O(4):N(3'),O(4')](pyridine-κN)cobalt(II)-4,4'-bipyridine (1/1).

In the title compound, [Co(C(13)H(10)N(4)O(8))(C(5)H(5)N)(H(2)O)]·C(10)H(8)N(2), the asymmetric unit comprises half a Co(II) complex located on a mirror plane and half a cocrystallized mol-ecule of 4,4'-bipyridine located on an inversion center. The Co(II) ion is six coordinate, with distorted octa-hedral geometry, ligated by two N atoms and two O atoms from a 2,2'-(propane-1,3-di-yl)bis-(5-carboxy-1H-imidazole-4-carboxyl-ate) dianion, one N atom from a pyridine mol-ecule and one coordinating water mol-ecule. The Co-O bond lengths range from 2.076 (2) to 2.1441 (15) Å, while the Co-N bond lengths are 2.138 (3) and 2.1515 (17) Å. A two-dimensional network of N-H⋯O and O-H⋯N hydrogen bonds stabilizes the crystal packing. There are π-π inter-actions between the bipyridine and imidazole rings [centroid-centroid distance = 3.7694 (4) Å]. The propane-1,3-diyl group is disordered over two conformations, with refined occupancies of 0.755 (8) and 0.245 (8).

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.
