PREPARATION OF NEW PHTHALOCYANINE COMPLEXES OF SOME RARE-EARTH ELEMENTS

Abstract The reaction of tris(1,3-diphenyl-1,3-propanedionato) complexes of heavier rare-earth elements, M3+(dbm)3 and lithium phthalocyaninato(2−), Li2(pc) gave two types of new stable phthalocyanine complexes, [M3+(pc) (dbm) (dbmH)] and [M3+(pc) (dbm)] depending on the solvents used for the preparation. The structure of both types of complexes are tentatively proposed.
