μ3-Iodido-tri-μ3-sulfido-tris[(triphenylphosphine)silver(I)][thioxotungsten(VI)] dichloromethane 0.45-solvate

Abstract

In the title complex, [WAg3IS4(C18H15P)3]·0.45CH2Cl2, the W atom has almost regular tetra­hedral coordination geometry, with one terminal and three triply bridging S atoms; the Ag atoms have tetra­hedral coordination geometry distorted by expanded P—Ag—S and contracted S—Ag—S angles, the fourth site being occupied by a triply bridging I atom. The bridging S and I atoms, together with the W and three Ag atoms, form a pseudo-cubane core with small angles at the non-metal vertices, resulting in short W⋯Ag distances. The dichloro­methane solvent mol­ecule is disordered over two inversion-related sites with common Cl-atom sites and with a refined occupancy factor of 0.449 (4) for each site.
