摘要：

The ester-substituted triscatechol ligand L-H-6 can be easily prepared in a triple imine condensation reaction. The required trisamine is prepared starting from diphenylamine and 2-bromobenzoic acid methylester. Upon coordination of titanium(IV) ions the tetrahedral M4L4 coordination compound is obtained, which due to the symmetry breaking substituent exists as a mixture of isomers. However, the complex can be unambiguously characterized by ESI-MS.
