摘要

It is well known that the M_2(mu-OOCR)_2fragment is present in active centers of many metalloenzymes responsible for different chemical processes in anture(redox reactins,oxygen transport,peptide bond hydrolysis,fixation and transformations of small molecules,etc).~(1-4)The synthesis of binuclear transition methal compolex with bridging carboxylated anions and studies of their structures and chemical and physical properties are important problems of modern coordination chemistry,because these compoundsare potential models of methal-containing fragments of natural enzymes.
