Abstract

Two novel homoleptic diazaporphyrinato lanthanide sandwich com-plexes M(2)(DAP)(3) [M = Ce (1), Eu (2); DAP= 2,8,12,18-tetra-ethyl-3,7,13,17-tetramethyl-5,15-diazaporphyrinate] were synthesized by a one-pot reaction of the corresponding M(acac)(3).nH(2)O (acac = acetylacetonate) with metal-free D(2)(h) type diazaporphyrin, H(2)DAP. The spectroscopic and electrochemical properties are compared with those of complexes based on D(4)(h) symmetry porphyrin ligands.
