Directed Synthesis of [Mo 3 S 13 ] 2− , an Isolated Cluster Containing Sulfur Atoms in Three Different States of Bonding

Transition metal-suffer clusters, possessing interest as model compounds for bioinorganic chemistry, have previously been prepared mainly by unusual reactions and in frequently low yields. The synthesis of (NH4)2[Mo3S(S2)6]·½H2O has now been accomplished in aqueous solution from MoCl4(py)2 and ammonium polysulfide.
