    Description / Table of Contents: Zusammenfassung Titanocenkomplexe ([Ti(η5-C5H4 R)2 X 2];R=H, SiMe3;X=Cl, Br) reagieren in wäßrigem Methanol mit Na2H2 EDTA unter Verdrängung der Halogen- und Cyclopentadienylliganden zum selben Produkt ([Ti(EDTA)(H2O)]). Die Struktur von ([Ti(EDTA)(H2O)]) wurde röntgenographisch bestimmt. Kristalldaten: monoklin,a=13.923(6),b=7.048(3),c=13.252(5) Å, β=90.81(1)°, RaumgruppeP21/c,Z=4. In diesem Komplex ist das Titanatom mit einem sechszähnigenEDTA-Liganden und einem Wassermolekül, das eine zusätzliche Koordinationsstelle besetzt, siebenfach koordiniert.
    Notes: Summary Titanocene complexes ([Ti(η5-C5H4 R)2 X 2];R = H, SiMe3;X=Cl, Br) react with Na2H2 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: monoclinica=13.923(6),b=7.048(3),c=13.252(5) Å, β=90.81(1)°, space groupP21/c,Z=4. In this complex, Ti has a sevenfold coordination with a hexadentateEDTA 4− ligand and a water molecule occupying an additional coordination site.
