摘　　要：Two cis-dicarbonyl rhodium complexes containing uncoordinated donors have been synthesized, and their IR and XPS data and the influence of their intramolecular substitution reaction on their stabilities have been reported. The intramolecular substitution reaction is reversible. Under the condition of heating and without the protection of CO, the uncoordinated donors substitute the terminal carbonyls on the rhodium to form tetradentated complex. So the rhodium complex will not decompose for the drop of the terminal carbonyls and its stability is enhanced. In atmosphere of CO, it recovers to bidentate complex.Two cis-dicarbonyl rhodium complexes containing uncoordinated donors have been synthesized, and their IR and XPS data and the influence of their intramolecular substitution reaction on their stabilities have been reported.
