Abstract

Molybdenum halides in lower oxidation states typically adopt dinuclear or polynuclear structures. Hexamolybdenum dodecachloride (Mo 6 Cl 12 ), its discrete halide and chalcogenide derivatives, and its coordination complexes have attracted considerable attention because of their interesting photochemical properties/lifetimes (phosphorescence, luminescence, and electrogenerated chemiluminescence), utility in catalysis, radiochemistry, sensor and conductor research, intercalation chemistry, and possible use as molecular precursors to chalcogenide‐based Chevrel‐phase materials. There has also been considerable theoretical effort to understand cluster bonding and photochemical lifetimes. There are a number of published procedures for the synthesis of Mo 6 Cl 12 . This chapter presents an extension of reduction methodology to the convenient preparation of tetradecachlorohexamolybdate hexahydrate (chloromolybdic acid) and Mo 6 Cl 12 .
