Crystal structure of bis(1,1,2,2-tetramethyldiphosphane-1,2-dithione-κ²S,S′)copper(I) tetrafluoridoborate

Abstract

In the title salt, [Cu(C4H12P2S2)2]BF4, both diphosphine di­sulfide mol­ecules bind to the CuI atom as chelating ligands via the S atoms, forming a monovalent cation with a slightly distorted tetra­hedral coordination around the CuI atom. The ligand chelate rings are twisted in opposite directions, with one in the λ and one in the δ configuration. In the crystal, possible C—H⋯F hydrogen bonds may stabilize the orientation.
