✦ Synopsis

A new type of amidinate ancillary ligand has been prepared, distortion of the amidinate nitrogen bearing the pendant functionality. With AlEt 2 Cl cocatalyst the compound 1 which incorporates a pendant tertiary amine functionality. The crystal structure of a vanadium(III) derivative, produces a single-site catalytic system for the polymerization of ethene. [SiMe 3 NC(Ph)NCH 2 CH 2 NMe 2 ]VCl 2 (THF) (1), shows that the ligand can adopt a facial geometry, with an unusual
