Abstract

Bimetal alkoxo complexes of rhenium, niobium, and tantalum with the general formula M4O2(OR)(14)(ReO4)(2), where M = Nb or Ta and R = Me or Et, were prepared in similar to 80% yield by reacting niobium or tantalum alkoxide M(OR)(5) (R = Me or Et) with rhenium heptoxide Re2O7 in toluene. Comparative analysis of the molecular structures of the complexes was carried out by means of single-crystal X-ray diffraction and IR spectroscopy. The effect of the organic ligand and crystallization temperature on the geometry of the perrhenate group was studied. The solubility of the aforementioned alkoxo complexes in organic solvents increases with increasing hydrocarbon chain length of the ligand
