Bis[bis­(2,2′-bi­pyridine-κ(2) N,N′)(carbon­ato-κ(2) O,O′)cobalt(III)] 2-{4-[(carboxyl­atometh­yl)carbamo­yl]benz­amido}­acetate hexa­hydrate

The complex cation of the title compound, [Co(CO(3))(C(10)H(8)N(2))(2)](2)(C(12)H(10)N(2)O(6))·6H(2)O, contains a Co(III) atom with a distorted octa­hedral coordination environment formed by four N atoms from two bidentate 2,2′-bi­pyridine ligands and one bidentate carbonate anion. The asymmetric unit is completed by one-half of the 2-({4-[(carboxyl­atometh­yl)carbamo­yl]phen­yl}formamido)­acetate dianion, which is located on a centre of inversion, and by three water mol­ecules. Two [Co(CO(3))(C(10)H(8)N(2))(2)](+) cations are connected through C—H⋯O contacts by the uncoordinating anions. The aromatic rings of the 2,2′-bi­pyridine ligands and di­acetate anions are involved in π–π stacking and C—H⋯π inter­actions. 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 supra­molecular network.
