J. Mizutani et al., SYNTHESES AND STRUCTURES OF TRINUCLEAR MOLYBDENUM CLUSTER COMPLEXES [MO3S4CL4(C5H5N)(5)] AND [MO3S4CL3(C5H5N)(6)]I, Bulletin of the Chemical Society of Japan, 71(3), 1998, pp. 631-636
A trinuclear molybdenum chloro sulfide cluster complex [Mo3S4Cl4(C5H5N
)(5)] (1) was synthesized by the excision of a nonmolecular cluster co
mpound Mo3S7Cl4 with triphenylphosphine and pyridine. Three molybdenum
atoms and four sulfur atoms form an incomplete cubane-type cluster co
re, which is coordinated by four chloro and five pyridine ligands. By
the reaction of 1 with I-2 in pyridine, [Mo3S4Cl3(C5H5N)(6)]I (2) was
synthesized. Three mu-S in the cluster cation and the iodine anion hav
e short contacts, within the sum of the van der Waals radii of sulfur
and iodine.
