The heterometallic cadmium-silver complex cis-bis[dicyanidoargentato(I)-κN]bis(5,5'-dimethyl-2,2'-bipyridyl-κ(2)N,N')cadmium(II) monohydrate.

In the title complex, [Ag2Cd(CN)4(C12H12N2)2]·H2O or cis-[Cd{Ag(CN)2}2(5,5'-dmbpy)2]·H2O, where 5,5'-dmbpy is 5,5'-dimethyl-2,2'-bipyridyl, the asymmetric unit consists of a discrete neutral [Cd{Ag(CN)2}2(5,5'-dmbpy)2] unit and a solvent water molecule. The Cd(II) cation is coordinated by two bidentate chelate 5,5'-dmbpy ligands and two monodentate [Ag(I)(CN)2](-) anions, which are in a cis arrangement around the Cd(II) cation, leading to an octahedral CdN6 geometry. The overall structure is stabilized by a combination of intermolecular hydrogen bonding, and Ag(I)···Ag(I) and π-π interactions, forming a three-dimensional supramolecular network.
