Exploring aurophilic interactions in P,C–Au(I)–Y complexes: Pathways to supramolecular aggregation

Abstract

In this chapter we provide an extensive overview of Au’s inclination to form supramolecular assemblies through the establishment of Au···Au contacts, mainly in the solid state. We have focused on P–Au–Y and C–Au–Y configurations (where Y is O, N, S, P, or a halogen atom) based on the expertize of our research groups. We first assess the natural tendency of linear Au(I) complexes to aggregate, supported by statistical evidence. The following sections are dedicated to analyzing the supramolecular structures resulting from P–Au–Y and C–Au–Y configurations, breaking down the analysis according to the specific Y atom. It should be noted that our approach is targeted, selecting instances that either highlight exceptional supramolecular structures or provide valuable insights through comparisons among different substituents or ligands. We have contemplated extending our findings to those reported in the literature by experts in the field. This would allow us to present a more comprehensive and expansive overview of our research.
