Abstract: The structure of the title compound, [Cd(dca)₂(bpno)₂(H₂O)₂], contains a Cd atom coordinated by bpno (4,4'-bipyridine N,N'-dioxide, C₁₀H₈N₂O₂), dca [dca is dicyanamide, N(CN)₂^-] and two water molecules. The central Cd^II ion is located at an inversion center, coordinated by two N atoms from dca, two O atoms from bpno and two O atoms from water molecules, in an approximately octahedral geometry. This discrete structure is further extended to form a two-dimensional layer structure involving weak hydrogen bonds. The compound is isostructural with its cobalt analog [Aneta, Zdirad, Augustin, Jiri & Marius (2003). Polyhedron, 22, 789-794].
