Synthesis and X-ray single crystal study of niobium and tantalum oxo-ethoxo-perrhenates, (M4O2)-O-V(OEt)(14)(ReO4)(2)
Nikonova OA, Kessler VG, Drobot DV, Shcheglov PA, Seisenbaeva GAAbstract
Niobium and tantalum oxo-ethoxo-perrhenates, (M4O2)-O-v(OEt)(14)(ReO4)(2), are easily obtained in high yields via interaction of metal ethoxides, M-v(OEt)(5), with rhenium heptoxide, Re2O7, in hydrocarbon solvents. The complexes have good solubility in hexane and toluene and are stable in solution at room temperature. Their molecular structures are based on a tetranuclear M-4(mu-O)(2)(mu-OR)(4)X-12 core, X = OR, ReO4, composed of two pairs of edge-sharing octahedra joined via two almost linear oxo-bridges containing a rectangular flat M-4-arrangement. The perrhenate ligands are attached in a centrosymmetric manner to the two opposite corners of the rectangle. (c) 2006 Elsevier Ltd. All rights reservedKeywords
