摘要：

Three titanium oxo-isopropoxo clusters Ti(6)O(4)(OOC-CH(3))(4)(OP(i))(12) (1), Ti(12)O(16)(OPr(i))(16) (2) and Ti(12)O(16)(OPr(i))(16). 1.4CH(2)Cl(2) (3) are obtained by refluxing Ti(OPr(i))(4) with 1.2 equivalents of carboxylic acids over two days. The molecular structures of Ti(6)O(4)(OOCCH(3))(4)(OPr(i))(12) (1) and Ti(12)O(16)(OPr(i))(16). 1.4CH(2)Cl(2) (3) have been resolved by single crystal X-ray diffraction. The titanium oxo organo cores of these clusters are also characterized in solution by (17)O NMR spectroscopy and in solid-state by (13)C CP MAS NMR spectroscopy. (C) 1998 Elsevier Science S.A.
