Lanthanide complexes with acetylacetonate and 5,10,15,20-tetra (4-(4-chlorobenzoyloxy) phenyl) porphyrin ligands

摘要

Lanthanide complexes of acetylacetonate and 5,10,15,20-tetra(4-(4-chlorobenzoyloxy)phenyl)porphyrin having the general formula Ln((ClBOP)_4P)(acac) (where Ln = Th, Ho. Er. Tm; ClBOP = (4-chlorobenzoyloxy)phenyl; Hacac = acetylacetone; P = porphyrin) have been prepared and characterized. A structure is proposed in which one 5,10,15,20-tetra(4-(4-chlorobenzoyloxy)phenyl) porphyrin is coordinated to a rare earth ion in a tetradentate fashion, while one acetylacetonate is coordinated to the same metal ion in a bidentate fashion.
