N—H...S and N—H...O hydrogen bonding in tetra-n-butylammonium (imidazolidine-2-thione-2κS)dioxo-1κ2O-di-μ-sulfido-1:2κ4S:S-copper(I)tungstate(VI)

Abstract

In the title complex, (C16H36N)[WCuO2S2(C3H6N2S)], the W and Cu atoms have tetra­hedral and trigonal-planar coordination, respectively. Two sulfide ligands bridge the two metal centres; tungsten is additionally coordinated by two terminal oxo ligands and copper by the exocyclic S atom of imidazolidine-2-thione. There is an intra­molecular N—H⋯S hydrogen bond in the anion, and anions are linked into chains by N—H⋯O inter­molecular hydrogen bonds. The more loosely held cation is disordered.
