Rezumat

A series of novel tri-, tetra- and pentanuclear complexes composed of dinuclear LM2 units (M=Co, Ni,Zn; L=24-membered macrocyclic hexaaza-dithiophenolate ligand) and ferrocene-carboxylate ([CpFeC5H4CO2]ˉ),1,1’-ferro-cenedicarboxylate([Fe(C5H4-CO2)2]2ˉ), acetylenedicarboxylate, terephthalate, isophthalate, and naphthalene diimide dicar-boxylate groups is reported. The complexes have been synthesized and characterised by UV/Vis-, IR-spectroscopy, and X-ray crystallography. Each dicarboxylate dianion acts as a quadridentate bridging ligand linking two bioctahedral LM2 units via μ1,3-bridging carboxylate functions to generate discrete dications with a central LM2(O2C-R-CO2)M2L core.
