(2,2'-Bipyridine-6,6'-dicarboxyl-ato-?(3)N,N',O(6))(6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ato-?(3)N,N',O(6))cobalt(III).

ABSTRACT: The Co(III) atom in the title compound, [Co(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is six-coordinated in a distorted octa-hedral geometry by four N atoms and two O atoms of the chelating 2,2'-bipyridine-6,6'-dicarboxyl-ate and 6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ate ligands. Intermolecular O-H?O hydrogen bonds and face-to-face ?-stacking inter-actions [centroid-centroid distance = 3.6352?(16)?Å] between inversion-related pyridine rings link adjacent mononuclear units into a two-dimensional supra-molecular structure, and several inter-molecular C-H?O inter-actions are also observed.
