摘      要：In this work,a series of titanium-oxo clusters functionalized by in sitw formed esterified ligands,Ti_(6)(μ_(2)-O)_(2)(μ_(3)-O)_(2)(O^(i)Pr)_(10)(0_(3)P-Phen)_(2)(THA^(i)Pr)_(2)(PTC-267;THA=cis-1,2,3,6-tetrahydrophthalic anhydride),Ti_(6)(μ_(2)-O)_(2)(μ_(3)-O)_(2)(O^(i)Pr)_(10)(0_(3)P-Phen)_(2)(THA^(i)Pr)_(2)(PTC-268 and PTC-269;PDA=3;4-pyridinedicarboxylic acid)and Ti_(6)(μ_(2)-O)_(2)(μ_(4)-O)_(2)(O^(i)Pr)_(10)(cat)_(2)(THA^(i)Pr)_(2)(PTC-270;cat=catechol),were successfully synthesized by one-step solvothermal ***-267,PTC-268 and PTC-269 possess a similar{Ti_(6)(μ_(2)-O)_(2)(μ_(3)-O)_(2)}core,while the core of PTC-270 is composed of a unique{Ti_(6)(μ_(4)-O)_(2)(μ_(2)-O)_(2)}***-268 and PTC-269 occur as geometric isomers with each ***,these complexes offer rare examples of dicarboxylate-modified polyoxo-titanium clusters(PTCs)with ester *** work not only offers an opportunity to gain an insight into the formation mechanism of PTCs,but also contributes to the exploration of optimal synthetic conditions for high-nuclearity PTCs.
