A new type of amidinate ancillary ligand has been prepared, which incorporates a pendant tertiary amine functionality. The crystal structure of a vanadium(III) derivative, [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 distortion of the amidinate nitrogen bearing the pendant functionality. With AlEt 2 Cl cocatalyst the compound 1 produces a single‐site catalytic system for the polymerization of ethene.
