| Abstract: | Ten new dinuclear cobalt complexes with general formular (RC2R')Co2(CO)(6-n)(PPh3)n have been synthesized and characterized by m.p., element analysis, IR and UV spectra. The influence of charge density on Co in complexes and steric hindrance of RC2R' on the reaction of PPh3 substituting CO in complexes has been studied and the shift of characterized absorbing peak in IR and UV spectra of the complexes has also been probed into from bonding. |

| Keywords: | dinuclear cobalt complex substituting reaction synthesis spectra |
