摘要：
Titanocene complexes ([Ti(eta(5)-C5H4R)(2)X-2]; R = H, SiMe3; X = Cl, Er) react with Na(2)H(2)EDTA in aqueous methanol to give an identical product ([Ti(EDTA)(H2O)] by cleavage of the halogen and cyclopentadienyl ligands. The structure of [Ti(EDTA)(H2O)] has been determined by X-ray diffraction; crystal data: monoclinic a = 13.923(6), b = 7.048(3), c = 13.252(5) Angstrom, beta = 90.81(1)degrees, space group P2(1)/c, Z = 4. In this complex, Ti has a sevenfold coordination with a hexadentate EDTA(4-) ligand and a water molecule occupying an additional coordination site.
