In the title compound, [Cd(C6H7N2O5)2], the Cd atom lies on an inversion center and has a slightly distorted octa­hedral geometry. The equatorial plane contains two bidentate 5-carb­oxy-2-methyl-1 H-imidazole-4-carboxyl­ate monoanionic ligands. Two coordinated water mol­ecules occupy the axial sites. Inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains, which are further connected by inter­molecular O—H⋯O hydrogen bonds, resulting in a three-dimensional supra­molecular framework.

The structure of the title compound, [Cu2Cl2(C10H8N2)] n, consists of a two-dimensional layer. Each Cl atom bridges three Cu atoms to form a ladder-like structure, whereas the 4,4′-bipyridine ligands form a link between Cu atoms of adjacent ladders, thus building a two-dimensional layer structure.
