Tris[ N , N -bis-(3,5-di- tert -butyl-benz-yl)di-thio-carbamato-κ 2 S , S ']-μ 3 -sulfido-tris-μ 2 -disulfido- triangulo -trimolybdenum(IV) iodide.

The title compound, [Mo 3 (C 31 H 46 NS 2 ) 3 S 7 ]I, crystallizes on a threefold rotational axis in P 31 c (space group No. 159). The [Mo 3 S 7 (S 2 CN(CH 2 C 6 H 3 -3,5- t Bu 2 ) 2 ) 3 ] + cations are arrayed in sheets in the ab plane with inter-ligand hydro-phobic inter-actions between tert -butyl groups guiding the packing arrangement. These cations form stacks parallel to the c axis with a separating distance of 10.9815 (6) Å (the c axis length) between the Mo 3 centroids. On the underside of the cluster, opposite the μ 3 -S 2- ligand, the iodide counteranion forms close contacts of 3.166 (2) Å with the sulfur atoms of the μ 2 -S 2 2- ligands. These contacts are less than the sum of the van der Waals radii of the atoms (1.8 and 2.1 Å for S and I, respectively), thus indicating an appreciable degree of covalency to the [Mo 3 S 7 (S 2 CN(CH 2 C 6 H 3 -3,5- t Bu 2 ) 2 ) 3 ] + ⋯I - inter-actions.
