STRUCTURE AND ABSOLUTE CONFIGURATION OF TRANS(O)-N,N′-ETHYLENEBIS-(S-METHYL-L-CYSTEINATO)COBALT(III) PERCHLORATE
The crystal structure of trans(O)-N,N′-ethylenebis(S-methyl-L-cysteinato)cobalt(III) perchlorate was determined by X-ray diffraction study. The structure consists of two kinds of complex cations with asymmetric sulfur atoms of different absolute configuration (S(S)S(S) and R(S)S(S)). The differences between the configurations of the sulfur atoms in crystal and those in solution are discussed.
