Novel titanocanes and spirobititanocanes based on 2,6-bis[hydroxy(diphenyl)methyl]pyridine (1a) and 2,6-di(hydroxymethyl)pyridine (1b) – [2,6-C5H3N(CPh2O)2]Ti(O-i-Pr)2 (2a), [2,6-C5H3N(CPh2O)2]2Ti (3a), [2,6-C5H3N(CH2O)2]2Ti (3b), [2,6-C5H3N(CPh2O)2]TiCl2 (4) – as well as the closely related N-phenyl derivative PhN(CH2CH2O)2Ti(Cl)Cp (5) have been synthesized. Complexes 2–5 were characterized by 1H and 13C NMR spectroscopy and elemental analysis data. The molecular structure of 3a was determined by X-ray structure analysis.
