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

摘要

Lanthanide complexes of acetylacetonate and 5, 10, 15, 20-tetra(para-(4-chloro-henzoyloxy)-meta-ethyloxy)phenyl porphyrin having the general formula Ln((ClBOEP)_4P)acac (where Ln = Tb, Dy, Ho, Er; ClBOEP = (para-(4-chlorobenzoy-loxy)-meta-ethyloxy)phenyl; Hacac = acetylacetone; P = porphyrin) have been prepared and characterized. A structure is proposed in which one 5, 10, 15, 20-tetra(para-(4-chloro-benzoyloxy)-meta-ethyloxy)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.
