Abstract: The title compound with [α]D20-87. 5°and yield 66% was prepared by the reaction of L-cysteine hydrochloride monohydrate and carbondisulfide in the presence of sodium hy-droxide and cupric sulfate hydrate. The crystal structure was determined by X-ray diffraction method. The crystal is orthorhombic system, space group Pz1z1z1, a=0.5029(2) nm, b=0. 7749(5) nm, c=1. 6300(5) nm, V=0. 6350(5) nm3, z=4. The electronic structure of the title compound was studied by molecular orbital PM3 method- The nature of the near frontier orbital and distribution of the calculated net charges and bond orders were obtained.The active site was described.
