Comlexes of chromium (III) with monodentate-coordination cysteine

摘要

The synthesis, structure and properties of chromium (III) cysteinates a series [Cr(H_2L)_6-(n+m)(H_2O)_nCl_m] Cl_3-m are described. It is shown, that monodentate coordination of cysteine occurs on a oxygen of carboxylic group. For complexes in diluted solutions cyclization on amino-group with replacement of H_2O Cl~- or cysteine molecules is observed.
