Di-[mu]-methanolato-bis[(2-tert-butyl-6-methylphenolato-[kappa]O)methyltitanium(IV)]

A. J. Nielson, C. Shen and J. M. Waters

Abstract: The molecule of the title compound, [Ti2(CH3)2(CH3O)2(C11H15O)4] or {[Ti(Me)([mu]-OCH3)(OC6H3CMe3-2-Me-6)]2}, has a centrosymmetric, dimeric structure with a distorted square pyramidal array about each titanium atom. The methoxide ligands form an asymmetric bridge between the two TiIV atoms [Ti-O bond lengths of 1.9794 (12) and 2.0603 (12) Å] with the two phenolato ligands occupying the remaining basal sites [Ti-O 1.8218 (11) and 1.8135 (11) Å]. The Ti-O-C phenolato bond angles are similar at 161.24 (10) and 160.66 (11)°. The methyl ligand attached to the metal atom has a Ti-C bond length of 2.0878 (17) Å.
