Abstract : Molybdenum(II) halides readily react with alcoholic solutions of either sodium methoxide or ethoxide at room temperature to give crystalline coordination compounds of the type Na2((Mo6X8)(OR)6) in which the (Mo6X8)(4+) cluster behaves like a hexacoordinate coordination center. More vigorous treatment of molybdenum(II) chloride with sodium methoxide in methanol yields the crystalline compound Na2((Mo6(OCH3)8)(OCH3)6) in which both ligand and cluster chloride ions are replaced by methoxy groups. This compound appears to contain the cluster (Mo6(OCH3)8)(4+) analogous to the well known (Mo6X8)(4+) on the basis of magnetic properties, oxidation state of the molybdenum, proton magnetic resonance, conductivity, molecular weight, and infrared spectra.
