Design and construction of active site of copper (I) proteins using pyrazole and dioxodithiotungstate anion ligands

The reaction of thiometallates anions [MO۲S۲]۲- (M=W,Mo) with d۱۰ metal ions and heterocyclicthione ligands , the variety of compounds are obtained that are important from simulate to copper and zincenzymes coordination active site of biological systems. For this reason, the complexes synthesized with theseligands in recent years have shown a strong metal-ligand interaction. Different thiometal compounds can betransformed into each other by chemical reactions because the number of oxygen and sulfur atoms around Wchanges. The reaction of (dioxo dithiotungstate anion) [WO۲S۲]۲- with CuCl and tetra ethyl ammonium bromideand heterocyclic ligands; Pyrazole (C۳H۴N۲) in acetone solvent yields the cluster complex[(Et۴N)WO۲S۲CuI(C۳H۴N۲)] that have been characterized by FT- IR, UV- Vis and ۱HNMR spectroscopies andelemental analysis (C.H.N).
