Two novel homoleptic diazaporphyrinato lanthanide sandwich com-plexes M2(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·nH2O (acac = acetylacetonate) with metal-free D2h type diazaporphyrin, H2DAP. The spectroscopic and electrochemical properties are compared with those of complexes based on D4h symmetry porphyrin ligands.
