In this paper, a novel metal-organic bidentate ligand was synthesized and the bimetallic complexes formed with Cd (II) and Hg (II) halides were synthesized by the bridging effect of ligands Their structures were characterized. The catalytic properties of these compounds for the reaction of CO2 with ethylene oxide to prepare ethylene carbonate were studied. The effects of reaction conditions were discussed. The experimental results showed that: (1) Under the same reaction conditions, in terms of the catalytic activity of the complex, Fe (CO) 3L2- (HgI2) 2> HgI2> Fe (CO) 3L2- (HgCl2) 2> ) 3L2> Fg (CO) 3L2-CdCl2 (L = PhMePpy). (2) For the same compound, the influence of reaction conditions is: high temperature and high pressure is conducive to the catalytic reaction.
