ZrX(4)(X = NMe(2), CH(2)Ph, CH(2)Bu(t)) yield zirconium aminopyridinates, usually of the type [ML(2)X(2)], some of which have been characterised by X-ray crystallography. Control of absolute configuration at the metal centre is pursued by investigation of the effects of chiral amine substituent, substitution at the pyridine rings and the identity of co-ligands. Surprisingly the conformationally flexible
