Abstract
- Simple synthetic routes for the preparation of octanuclear oxomolybdenum(V) clusters with stoichiometry [Mo8O16(OCH3)8L4] (L=4-methylpyridine (4-MePy) (a), 4-ethylpyridine (4-EtPy) (b), 4-tert-butylpyridine (4-ButPy) (c), pyridine (Py) (d), 3-methylpyridine (3-MePy) (e), 3,5-lutidine (3,5-Lut) (f)) are described. Crystal structures of e and f were investigated by X-ray diffraction. The puckered ring structure made up of eight molybdenum atoms linked together by pairs of methoxy groups and pairs of oxo groups was recognized in both. The solubility of the compounds in pyridines was employed for the substitution of coordinated pyridine for a different pyridine. The octanuclear clusters have been found to react in pyridines at elevated temperatures to oxomolybdenum(V,VI) clusters with the formula [Mo10O26L8].
