✦ Synopsis

Metal ion complexes

of polyaza macrocyclic ligands have been the subject of extensive investigations over the past decade [2-S] ; however, there are very few reports of scandium(II1) complexes containing these ligands in spite of the demonstrated ability of the scandium(II1) ion to form strong complexes with nitrogen donor ligands [6,7] . Complexes of Sc(II1) with the octaethylporphyrin dianion [8,9] and the phthalocyanine dianion [lo, 1 l] have been synthesized and studied although there have been no published reports concerning scandium(II1) complexes with the newer "synthetic" polyaza macrocyclic ligands.

As part of our overall program concerning the coordination chemistry of scandium, we report here the synthesis and characterization of some scandium (III) complexes containing the neutral macrocyclic ligands Me,Bz, [ 141 tetraeneNJ, I and Me4 [ 141 tetra-eneN,, II.
