Tris­[di­phenyl(2-pyridyl)­phosphine]-μ₃-iodo-tri-μ₃-sulfido-sulfidotrisilvertungsten di­chloro­methane hemisolvate

The title compound, [Ag₃WIS₄(C₁₇H₁₄NP)₃]·0.5CH₂Cl₂, is a cubane-type heterometallic cluster containing di­phenyl(2-pyridyl)­phosphine (Ph₂PPy). The pyridyl group of Ph₂PPy remains uncoordinated, so the Ph₂PPy ligand is monodentate and coordinates to one Ag atom. The W atom and three Ag atoms form a distorted tetrahedral geometry, capped by one I atom and three S atoms.
