Bis[tris-(diiso-butyl-dithio-carbamato)-μ 3 -sulfido-tri-μ 2 -di-sulfido-trimolybdenum(IV)] sulfide tetra-hydro-furan monosolvate.

The title compound, [Mo 3 (C 9 H 18 NS 2 ) 3 (S 2 ) 3 S] 2 S, crystallizes on a general position in the monoclinic space group P 2 1 / n (No. 14). The cationic [Mo 3 S 7 (S 2 CN i Bu 2 ) 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 Mo 3 plane opposite the μ 3 2- ligand. The two Mo 3 planes are inclined at an angle of 40.637 (15)°, which gives the assembly an open clamshell-like appearance. One μ 6 -S 2- ⋯S 2 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.
