description | The title compound, [[Ti(C(2)H(10)N)(2)(C(11)H(10)N(3))(2)] or Ti(C(11)H(10)N(3))(2)(NEt(2))(2)], was prepared by direct reaction of 2-(N-phenylmethyliminomethyl)-1H-imidazole and [Ti(NEt(2))(4)]. The Ti(IV) atom is in a pseudo-octahedral coordination environment with the imidazolido-group N-atoms occupying apical positions and amido- and imino-N-atoms cis-located in the equatorial plane. The presence of two bidentate chelating ligands determines the chirality of the Ti(IV) atom. The crystallographically independent unit, except for its phenyl rings, adopts nearly pseudo-C (2) symmetry (rotation around a twofold axis passing through the Ti atom and the centre of the imino-N⋯imino-N segment). The Ti—N(amido), Ti—N(imidazolido), and Ti—N(imino) bond lengths essentially differ, increasing by approximately 0.2 Å in the series. All ligating N atoms are in a nearly planar environment, which is indicative of additional pπ–dπ donations towards the metal atom. The two diazametallacyclic units are planar within 0.03 and 0.05 Å. |
