A quasi-layer structure of trinuclear molybdenum(IV) cluster, [Mo3S7(S2CNEt2)(3)]I center dot S-8

The title compound, [Mo-3(mu(3)-S)(mu-S-2)(3)(S2CNEt2)(3)]I . S-8, was obta ined by solid state reaction of (NH4)(2)MoS4, Et2NCS2Na, and Et4NI at low h eating temperature and crystallizes in space group P (1) over bar with a = 13.572(3), b = 13.813(4), c = 13.239(3) Angstrom, alpha = 92.63(3), beta = 100.15(3), gamma = 117.89(2)degrees, V = 2136(2) Angstrom(3), and D-calc. = 2.08 g/cm(3) for Z = 2. The structure reveals that it consists of a trinuc lear Mo cluster molecule, [Mo3S7(S2CNEt2)(3)]I, and one S-8, which are conn ected to form a quasi-layer structure by the interaction between S-8 and th e S atoms of the cluster molecule.
