| Research Abstract |
Aiming at developing new oligonuclear metal complexes, some multidentate, macrocyclic, and carboxylato ligands were utilized for producing such compounds. Linear and cyclic trinuclear metal complexes as well as chain complexes were synthesized by the use of four kinds of thiolic ligands having NNS-donor sets.Heterometal trinuclear complexes were also isolated. A new NNSS-donor thiolic ligand was synthsized to give adamantane-like tetranuclear complexes. Tetranuclear, pentanuclear, hexanuclear, and octanuclear complexes were synthesized by reaction of pentadentate ligands with various metal salts. Magnetic properties of these complexes are antiferromagnetic. Macrocyclic ligands afforded dinuclear and tetranuclear complexes. Metal carboxylate dimers were examined as building blocks for oligonuclear or polynuclear formation. In most cases, chain complexes were formed. A microporous structure was found in chain complex of copper(II) benzoate. Treatment of copper(II) carboxylates led to tetranuclear and hexanuclear complexes with alternating mu-carboxylato- and mu-alkoxo-bridges.
