  Structural and thermal stability studies of Ti(IV) hexanuclear oxo trimethylacetato isopropoxide complex

  摘要：

  A new titanium hexanuclear oxo carboxylato alkoxide complex, with the general formula [Ti6O6(OPr')(6)(OOCBu')(6)] (1), has been synthesized in a reaction of titanium isopropoxide (Ti(OPri)(4)) with Bu'COOH in the ratio 1:1. The structure was analyzed with the elemental analysis, IR and NMR spectroscopy, and X-ray single-crystal diffraction methods. Crystal structure of 1 was solved in the trigonal centrosymmetric system R (3) over barr. Titanium atoms form the hexanuclear cluster, where three mu(3)-oxo, two mu-carboxylato bridges and the terminal alkoxide ligand, in the distorted octahedron, surround each central cation. Analysis of spectroscopic data revealed a significant nonequivalence of interactions formed by the carboxylate groups, resulting from the asymmetry of Ti-mu-OOC bonds of carboxylate bridges in the complex molecule. TGA and MS studies suggest that volatile, titanium hexanuclear species may be formed between 423 and 553 K. (C) 2004 Elsevier B.V. All rights reserved.
