摘要：
<正> Dialkylphosphoric or dialkyphosphonic acids are important extractants for separa-tion of cobalt and nickel.The extraction mechanism and the composition of the ext-racted species have been studies by several authors（1-3）.But so far no X-ray struc-tural determination of these extracted complexes has been reported in the literature. In the present investigation,a new mixed ligand dinuclear cobalt complex withdibutylphosphoric acid and pyridine was prepared.The results of elemental analysisshow that the compound may be represented by Co（DBP）2·3Py·CHCl3.The magneticmoment of this comples was determined to be 4.79 Bohr magnetons, correponding tothree unpaired electrons per each cobalt atom.
