Table of Contents Entry. Gold(I) Phosphanyl Complexes, such as [Au(PR2)]n, have been known for more than 25 years. However, the solid-state structure of such complexes, as well as their nature in solution, has remained somewhat of a mystery. The figure displays the cyclic and polymeric forms that are possible (L=endgroup). The structures of the complexes, and the occurrence of Au:Au interactions are discussed.
