Reactions of AgI with salts of [WS4]2- or [MoS 4]2- and with either imidazolidine-2-thione (Imt) or [1,3]diazepane-2-thione (Diap) give the complexes [WS4Ag 2(Imt)2]n and [MS4Ag 2(Diap)4] [M = W or Mo]; in the case of Diap, corresponding Cu complexes can be obtained with CuCl instead of AgI. Decomposition of the Ag-Diap complexes during attempted recrystallisation leads to the polymeric complex [AgI(Diap)]n. The monomeric mixed-metal Diap complexes contain edge-sharing WS4 and AgS4 tetrahedra, the Diap ligands being terminally bonded to Ag through sulfur. The mixed-metal W-Ag-Imt complex is a chain polymer with two different environments for the WS4 unit and three different coordination environments for Ag, one of which is an unprecedented AgS5 square-based pyramid; Imt ligands are terminally coordinated to Ag. [AgI(Diap)]n has a complex polymeric chain structure with three different distorted tetrahedral environments for Ag, direct Ag-Ag bonding, both bridging and terminal I, and all Diap ligands bridging pairs of Ag atoms. All the crystal structures feature N-H⋯S or N-H⋯I hydrogen bonding. The complexes have also been characterised by infrared, UV-Vis and 1H and 13C NMR spectroscopy. © The Royal Society of Chemistry.
