Crystal structure of bis-(1,1,2,2-tetra-methyl-diphosphane-1,2-di-thione-κ(2) S,S')copper(I) tetra-fluorido-borate.

ABSTRACT: In the title compound, [Cu(C4H12P2S2)2]BF4, both diphosphine di-sulfide mol-ecules bind to the Cu(I) atom, as chelating ligands via the S atoms, forming a monovalent cation with a slightly distorted tetra-hedral coordination around the Cu(I) atom. The average Cu-S distance is 2.350 (15) Å, with small but possibly significant differences within each chelate ring. Ligand P=S distances average 1.964 (3) Å, and the P-P distances are 2.2262 (13) and 2.2166 (14) Å. The ligand chelate rings are twisted in opposite directions, with one in the λ and one in the δ configuration. Although the anisotropic displacement parameters of the F atoms of the anion are quite large compared to that of the B atom, difference Fourier syntheses indicate only one set of sites for the F atoms. In the crystal, possible C-H⋯F hydrogen bonds may stabilize the orientation. The B-F distances, uncorrected for libration, average 1.359 (6) Å.
