Reaction of the titanium imido complexes [Ti(NR)Cl2(py)3] (R = But, C6H3Me2-2,6 or C6H3Pri2-2,6; py = pyridine) with 2 equivalents of lithium aryloxide Li[OC6H3R′2-2,6] (R′ = Me, Pri or But) afforded the mononuclear four-or five-co-ordinate or binuclear four-co-ordinate complexes [{Ti(NR)(OC6H3R′2-2,6) 2(py)n}m] (m = 1, n = 1 or 2; m = 2, n = 0) depending on the identity of R and R′. The crystal structures of [Ti2(μ-NBut)2(OC6H 3Me2-2,6)4] 1 and [Ti(NC6H3Me2-2,6)(OC6H 3Me2-2,6)2(py)2] have been determined. Extended-Hueckel molecular orbital calculations for models of 1 showed that the deviation of the μ-imido But substituents from coplanarity with the Ti2N2 core in this and some related species can be attributed to a second-order Jahn-Teller distortion.
