Electrochemical properties of copper(I) halides andsubstituted thiourea complexes

摘要

The complexes between copper(I) halides and N,N'-diphenylthiourea have been investigated by cyclicvoltammetry to compare their structure and behaviour in solid state with those in solution. The halides under investigationinclude chloride, bromide, and iodide. Chloride and bromide complexes did not show the redox reaction, suggesting thatthey formed the strongest bond with the metal and hence the oxidation was inhibited. In contrast, iodide behaved differentlybecause of the two peaks of halide and trihalide oxidations. One peak disappeared, leaving the other halide-oxidized peakshifted to a more positive voltage due to the bonding with the metal. In solution, all complexes of N,N' -diphenylthioureawere derived from the oxidation process and exhibited oxidation potentials shifted to positive values.
