✦ Synopsis

Ligands containing multiple binding sites are of interest for the construction of structural and reactivity models of certain metallobiomolecules as well as polyelectronic systems."' The ligand 3,6-bis(T-pyridyI)pyridazine (dppn)Iz1 complexes a variety of metal ions,[3] and given our interest in dicopper-containing proteins, the binuclear copper(I1) complexes of dppn attracted our attention.I4I Therefore, we studied the interaction of copper(1) ions with this ligand and report here the structure and some properties of the resultant complexes. 4 3 8 8' 3' 4' 6 6' Scheme 1 Structure of the dppn hgand. The numbering is based on the interpretation of its NMR spectra.

1,4,7,1O-Tetraazacyclododecane having P-ethylphosphoryl pendant groups on the nitrogen atoms can form a complementary ligand for the Cu cation. It gives rise to a square pyramidal complex of [CuLI2+ compositions, the ligand entering this complex with a slight energy strain. 0 1996 John Wiley & Sons,
