Abstract

The sixteen neutral ML2 complexes of Co, Ni, Cu and Zn (II) with the p-toluenesulfonamide and trifluoromethylsulfonamide derivatives of 2-aminomethylpyridine (L1, L2) and its 6-Me homologue (L3, L4) have been characterised by low temperature X-ray crystallography (100– 120 K). Complexes of Co and Zn invariantly adopted a distorted tetrahedral geometry and whilst Cu (II) complexes of L2, L3 and L4 also took up a distorted tetrahedral geometry, ...
