Synthesis and Magnetic Properties of Oligonuclear Metal Complexes

为了开发新的寡核金属配合物，一些多齿配体、大环配体和羧基配体被用于生产这类化合物。采用四种具有nns给体的硫代配体合成了线性和环状三核金属配合物以及链式配合物。异金属三核配合物也被分离出来。合成了一种新的nnss给体巯基配体，得到了类似金刚烷的四核配合物。五齿配体与各种金属盐反应可合成四核、五核、六核和八核配合物。这些配合物的磁性是反铁磁性的。大环配体提供双核和四核配合物。研究了金属羧酸二聚体作为寡核或多核形成的基石。在大多数情况下，形成链式配合物。在苯甲酸铜络合物中发现了微孔结构。铜（II）羧酸盐的处理可以得到四核和六核配合物，这些配合物具有羧基和烷氧基交替桥。

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.
