摘要

On photolysis of [Co(L-cysi-N, S)₃]3- (L-cysi=L-cysteinesulfinate(2-) ion, cysi=NH₂CH(COO-)CH₂SO₂-), linkage isomerization from sulfinato-S to sulfinato-O took place to yield a mixture of [Co(L-cysi-N, S)_3-n(L-cysi-N, O)_n]3- (n=1, 2, 3). [Co(L-cysi-N, S)₂(L-cysi-N, O)]3-, one of the linkage isomers, was isolated and its structure was assigned on the basis of the absorption, circular dichroism, and 1H NMR spectra. This complex is thermally unstable and reverts to the starting complex.
