摘要：

The trititanate [Ti3O](OPri)(9)(OMe) was isolated from the reaction of Ti(OPri)(4) with water and methanol in isopropanol solution and characterized by elemental analysis, multinuclear NMR spectroscopy, and single-crystal X-ray diffraction (a=23.295(5), b=19.560(4), c=18.661(4) Angstrom, beta=108.39(3)degrees; Z=8; space group P2(1)/c-C-2h(5)). The [Ti3O](OPri)(9)(OMe) molecule has a Ti-3(mu(3)-O)(mu(3)-OMe)(mu(2)-OPri)(3)(OPri)(6) structure in the solid state and in solution, but is unstable in solution at ambient temperature even in hydrocarbon solvents where it is in quasi-equilibrium with Ti(OPri)(4-x)(OMe)(x), [Ti3O](OPri)(10), and more highly condensed polytitanates. The isostructural trititanate [Ti3O](OPri)(10) could not be isolated from isopropanol solutions of hydrolyzed Ti(OPri)(4),but was identified as the sole hydrolysis product at low degrees of hydrolysis using O-17, C-13{H-1} and H-1 NMR spectroscopy.
