Experiments conducted in the gas phase have led to the formation of a series of stable gold(II)
complexes with nitrogen- and oxygen-containing ligands. Such complexes are very rare in condensed-phase
chemistry. However, there is also a significant group of potential ligands, for example, H2O and NH3, for
which stable complexes could not be formed. There are strong similarities between these observations and
earlier results presented for silver(II), but both metal ions behave markedly different from copper(II). As a
group the majority of successful gold(II) ligands are characterized by being good ó donor-ð acceptor molecules;
however, it is also possible to understand the ability of individual ligands to stabilize the metal ion in terms
of a simple electrostatic model. Application of the latter reveals a semiquantitative trend between the physical
properties of a ligand, e.g. ionization energy, dipole moment, and polarizability, and the ligand’s ability to
stabilize either Cu(II), Ag(II), or Au(II). The model successfully accounts for the preference of Cu(II) for
aqueous chemistry, in comparison to the complete absence of such behavior on the part of Ag(II) and Au(II).
Ligands from recent examples of stable condensed-phase gold(II) complexes appear to meet at least one of the
criteria identified from the model
