2C:N;2N:C-(2-N,N,N',N'-tetramethylthiourea-2S:S)disilver(I)]Abstract: The title compound, [Ag2(CN)2(C5H12N2S)]n, crystallizes as an infinite three-dimensional framework structure. It exists in an unusual ionic form, the asymmetric unit being composed of a cation [(-tetramethylthiourea-S)Ag]+ and an anion [(Ag(CN)2]-. The thiourea S atom is coordinated asymmetrically to silver ions, linking two almost parallel chains. The same silver atom is linked to a symmetry-related atom by the [Ag(CN)2]- anion. In this way, a three-dimensional structure is built up. The shortest Ag
Ag intermolecular contact distance involves the silver atom in the [Ag(CN)2]- anion [AgAg 3.6965 (5) Å].
