Abstract

The complex cation of the title compound, [Co(CO3)(C10H8N2)2]2(C12H10N2O6)·6H2O, contains a Co(III) atom with a distorted octa-hedral coordination environment formed by four N atoms from two bidentate 2,2'-bi-pyridine ligands and one bidentate carbonate anion. The asymmetric unit is completed by one-half of the 2-({4-[(carboxyl-atometh-yl)carbamo-yl]phen-yl}formamido)-acetate dianion, which is located on a centre of inversion, and by three water mol-ecules. Two [Co(CO3)(C10H8N2)2](+) cations are connected through C-H⋯O contacts by the uncoordinating anions. The aromatic rings of the 2,2'-bi-pyridine ligands and di-acetate anions are involved in π-π stacking and C-H⋯π inter-actions. The centroid-centroid distances are in the range 3.4898 (4)-3.6384 (5) Å. The crystal structure is stabilized by further O-H⋯O and N-H⋯O hydrogen bonds, which give rise to a three-dimensional supra-molecular network.
