metal-organic compounds
The structures of two different complexes of silver(I) and dimethylthiourea (dmtu) in the stoichiometric ratios 1:2, [Ag(C3H8N2S)2]ClO4, and 1:3, [Ag(C3H8N2S)3]ClO4, are described. The 1:2 complex consists of polynuclear cationic chains, whereas the 1:3 complex contains discrete [Ag2(dmtu)6]2+ cations. In both structures, Ag2S2 lozenges with different Ag-S bond lengths are observed and the perchlorate anions are connected to the cations by hydrogen bonds.
