Abstract
The complex cation of the title compound, [Co(CO3)(C10H8N2)2]2(C12H10N2O6)·6H2O, contains a CoIII 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(CO3)(C10H8N2)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.
