Abstract

Combined TG/DTA techniques have been used to study the thermal decomposition of R3PAuCN (where R is ethyl, cyclohexyl, o-tolyl, m-tolyl, p-tolyl, allyl, cyanoethyl, 1-naphthyl and phenyl) complexes. It was observed that all of these complexes underwant decomposition cum redox reactions in the range of 200-600°C with evolution of both trans ligands, which are phosphine and cyanide, leaving metallic gold as a residue. The thermal decomposition of o-Tol3PAuCN has revealed that this is a stepwise process. In the first step decomposition takes place with evolution of phosphine and generation of AuCN, which in second step undergoes a redox reaction to produce metallic gold. The DTA curves have also confirmed these results.
