The Heterometallic Cadmium-Silver Complex Cis-Bis[Dicyanidoargentato(I)-Kappa N]Bis(5,5 '-Dimethyl-2,2 '-Bipyridyl-Kappa N-2,N ')Cadmium(Ii) Monohydrate

In the title complex, [Ag2Cd(CN)(4)(C12H12N2)(2)]center dot H2O or cis-[Cd{Ag(CN)(2)}(2)(5,5'-dmbpy)(2)]center dot 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 center dot center dot center dot Ag-I and pi-pi interactions, forming a three-dimensional supramolecular network.
