isolated. The Ni2+ complexes are high-spin and six-co-ordinate, and the Cu2+ complexes five-co-ordinate. 13C N.m.r. spectroscopy shows [Zn(L2)(dmso)][ClO4]2 to be a 2 : 1 mixture of two species, one symmetric and the other asymmetric, whilst in [Zn(L3)][ClO4]2 only ca. 10% of the asymmetric species is present in nitromethane solution. X-Ray crystallography has been used to dermine the structure of the symmetric
