The Chemistry of the Extraction of Gold - SAIMM

2011-5-29  All known gold(III) complexes have the low-spin 4P45d8 electronic con­ figuration and are also diamagnetic. The preferred co-ordination number of gold(I) is 2 and that of gold(III) is 4, with gold(I) tending to form linear complexes and gold(III) tending to form square planar complexes. For example, the cyanide complexes of gold(I)
