Abstract
SINCE 1963 there have been several reports of the existence of trimeric clusters of rhenium atoms in anionic and uncharged halogen compounds of rhenium (III)1–5. Recently, Dr. R. Colton and Prof. R. L. Martin have adduced magnetic and spectral evidence for the existence of trinuclear clusters in rhenium (IV) chloride6 and also in molybdenum (III) chloride7. In an investigation of the reactions of molybdenum hexafluoride as outlined in the following paragraph, a new mixed halide of molybdenum has been isolated and characterized. Magnetic, spectral and conductance measurements indicate that this compound is ionic and contains the (MoIV3Cl9)3+ cation, an entity which fits very well into the scheme proposed by Colton and Martin for stable clusters in molybdenum–chlorine compounds.
