Abstract

A novel aurous complex containing thiourea and thiocyanate as the mixed ligands is synthesized by the ISRC method in this paper. Its formula is determined as [Au (tu)2 ]SCN H2O by elemental analysis. The electrochemistry studies show it is a typical ionic compound and its conductivity reaches 13×10-4 Sm2mol-1. TG studies and related stability tests reveal the compound is excellently stable. By using single factors experiments the optimal plating index has been gotten and they are: pH=1.5~3.5, [A =1.5~2.5 g/L, temperature 30~50°C and plating time 10 minutes respectively. It is a competitive gold complex and will be find a wide application in electroplating, chemical deposition, ceramic decoration and other related areas.
