Abstract
The reaction of both histamine (hista) and cysteine (cys) with aqueous CuCN /S2O32- produced Cu(II) ion. In the histamine case thiocyanate ion was also created leading to the production of Cu(SCN)(2)(hista)(2). With cysteine, the 2-amino-2-thiazoline-4-carboxylic acid (atca) ligand was created leadin g to the production of Cu(atca)(2)(H2O). The crystal structures of the two complexes are discussed, and pathways for the production of thiocyanate and the atca ligand are proposed.
