Abstract
Complexes of the type [CuL2X2][L = 2-(3,3-dimethyl-2-thiabutyl)pyridine; X = Cl, Br, ClO4, or BF4], [CuL2X]-BF4(X = Cl or Br), [ML2X2](M = Co or Ni, X = Cl or Br), [ML2(H2O)(ClO4)]ClO4(M = Co or Ni), and [NiL2-(H2O)2][ClO4]2 have been prepared and characterized by electronic, i.r., and e.s.r. spectroscopy. It is proposed that in the solid state all the complexes have distorted octahedral structures except [CuL2X]BF4 complexes which are five-co-ordinate. In methanol the [CuL2X2](X = Cl or Br) complexes ionize to give [CuL2X]+ species whereas for X = ClO4 and BF4 the complexes also show evidence of ligand dissociation.Keywords
