“…In contrast, in the case of non-tertiary phosphines, the number of examples of gold complexes decreases considerably, a fact that could presumably be attributed to the relatively lower stability of these ligands compared with the former. The number of examples arising from the deprotonation of secondary or primary phosphines, those called phosphides, is also very scarce, especially in the case of gold(III) [1][2][3][4][5][6][7][8][9]. In fact, nowadays, this is still a pending subject that requires much more work because polynuclear phosphide complexes are expected to show catalytic activity, and because the strong donor and bridging abilities of PR 2 − groups can facilitate the proximity of gold centers at short distances, in turn facilitating the optical or sensing properties associated with this effect [10].…”

The synthesis of gold(III) and gold(I)–gold(III) complexes with phosphide bridges is still a matter that requires solutions for their marked instability, in spite of the affinity of this metal in both oxidation states for phosphorous donor ligands. In the course of our studies, we realized that the presence of perhalophenyl groups of the type pentafluorophenyl or 3,5-dichlorotrifluorophenyl in the complexes gives rise to an increase in their stability that eases their isolation and structural characterization. In this paper, we describe two new fully characterized neutral compounds of this type to extend the knowledge on this family of compounds, [{Au(C6Cl2F3)2}2(µ-PPh2)2] (1) and [{Au(C6Cl2F3)2(µ-PPh2)2Au}2] (2). In this work, we analyze the role of the perhalophenyl groups in the stability of these complexes by using quantum chemical topology methodologies, specifically employing an analysis of the non-covalent interactions (NCIs) in real space and evaluating the electrostatic potential surfaces (ESP). Our findings reveal the existence of appreciable π-stacking interactions among the perhalophenyl and phenyl groups in both compounds, significantly contributing to the stability of the systems.

In Part 1 of this chapter, the alkali metal coordination compounds are reviewed, starting with mixed-metal ZnLi species, the interest in which has grown out of their synthetic importance as bases, and metallocene systems, including cyclopentadienyl derivatives. Cases of extreme interest notwithstanding, discussion is limited to compounds that contain at least one carbon-alkali metal interaction. Part 2 provides an overview of the latest developments in coinage metal organometallic chemistry. Aiming to reflect the balance between different areas of the most recent research, a review of copper-based metal-organic frameworks and coordination polymers is followed by compounds of more general interest. Similarly, for silver and gold, polymeric structures and coordination frameworks are described, along with carbene complexes and, for gold, phosphine complexes. As for Part 1, the emphasis is placed on systems that contain at least one carbon-metal interaction. The analytical discussion focuses on solid-state investigations and, where appropriate, applications are mentioned along with structural results.
