New titanium(IV) complexes of the chelating ligand N,N‘-bis(3,5-dimethylphenyl)-phenanthrene-9,10-diamide (pada2-) are described. Metalation of padaH2 with TiCl4 in the presence of base afforded the six-coordinate pyridineadduct (pada)TiCl2(py)2 (1), which was used as a starting point for all further complexes presented in this work. Metathesis of 1 with LiN(SiMe3)2 afforded the four-coordinate complex
