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

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 [pi]-[pi] stacking and C-H...[pi] 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.
