摘要：

The reaction of [TiCl3(thf)(3)] with 4 equiv. of PhCO(2)H in refluxing thf or 3 equiv. of Cl- in CH2Cl2 gives [Ti2OCl3(O(2)CPh)(2)(thf)(3)] 1 and [NEt(4)](3)[Ti2Cl9] 2, respectively: crystallography shows them to possess trapped-valence [Ti-2(mu-O)(mu-O(2)CPh)(2)](3+) ((TiTIV)-T-III) and [Ti-2(mu l)(3)](3+) cores, respectively, the former with an unusual asymmetrically bridging O2- displaying triple/single bond distances to the metal ions.
