Copper can form four complexes with up to four cyanide ligands. The distribution of the cyano complexes depends on conditions such as cyanide concentration and pH, as shown in Figure 43.1.The distribution of the various species as a function of pH and sodium cyanide concentration indicates that high pH and free-cyanide conditions low HCN favor the formation of the higher-order copper I ...
