Cyclopentadienyl-hydrazido titanium complexes: Tuning of coordination modes of hydrazido ligands to the titanium center

Cyclopentadienyl-hydrazido titanium complexes [(eta(5)-C5Me4)SiMe2(NNMe2)]TiR2 (R = NMe2 (2), Cl (3), Me (5)) and [(eta(5)-C5Me4)SiMe2(NNMe2AlMe3]TiMe2 (4) have been prepared: and characterized. Single-crystal X-ray diffraction studies reveal that complexes 2-5 contain eta(1)-hydrazido (2 and 4) and eta(2)-hydrazido (3 and 5) groups depending on the electronic nature of the titanium center. The reaction of 2 with H2O produces a tetrameric organotitanoxane [(eta(5)-C5Me4)(SiMe2NHNMe2)Ti](4)O-6 (6) with an adamantane-like cage structure.
