Abstract

The title compound, [Mo₃(C₉H₁₈NS₂)₃(S₂)₃S]₂S, crystallizes on a general position in the monoclinic space group P2₁/n (No. 14). The cationic [Mo₃S₇(S₂CNⁱBu₂)₃]⁺ fragments are joined by a mono-sulfide dianion that forms close S⋯S contacts to each of the di-sulfide ligands on the side of the Mo₃ plane opposite the μ₃ ^2- ligand. The two Mo₃ planes are inclined at an angle of 40.637 (15)°, which gives the assembly an open clamshell-like appearance. One μ₆-S^2-⋯S₂ ^2- contact, at 2.4849 (14) Å, is appreciably shorter than the remaining five, which are in the range 2.7252 (13)-2.8077 (14) Å.

Keywords: crystal structure; dithiocarbamate ligand; molybdenum sulfide cluster; μ6-sulfide ligand.
