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 WAg 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.
