The isolation of some new three- and four-co-ordinate gold(I) complexes is reported. 197Au Moessbauer data are given for two-, three-, and four co-ordinate complexes, and the technique is shown to be well suited to the determination of co-ordination numbers.For the two- and three-co-ordinate systems the point-charge (partial quadrupole splitting) approach works well, provided that the structures are regular. 31P- n.m.r. data for the Au(1+)-P(C6H11)Ph2 system show that a maximum of three ligands can be bound to the cation.Data for this and other ligands are correlated with the ligand cone angles.Inconsistences between the species present in solution and those obtained by crystallisation are discussed.
