The [Co(pydc)2]2− anion is a six-coordinate CoII complex with a distorted octahedral coordination geometry. The structure also contains hexaaquacobalt(II) cations (site symmetry overline{1}), (tataH)+ cations and uncoordinated water molecules. The two(pydc)2− ligands in each [Co(pydc)2]2− anion are almost perpendicular to each other [dihedral angle between their mean planes = 82.3 (1)°].
