A diphosphine chelate ligand with a wide and flexible bite angle, a unique stereochemical environment, and redox-active and ambiphilic character is reported. Initially generated as its HgCl2 complex by reaction of 1,2-fc(PPh2)(SnMe3) (fc=ferrocenediyl) with HgCl2 in acetone, treatment with [n-Bu4N]CN readily liberates the free chiral bidentate ligand. An intermolecular ClHg?Cl→Hgfc2 (2.9929(13) ?) interaction that is unprecedented in ambiphilic ligand chemistry is seen in the solid structure of Hg(fcPPh2)2?HgCl2 where the bridging mercury atom acts as a σ-acceptor. Furthermore, a bis-[Rh(COD)Cl] complex is introduced, which displays relatively short Rh???Hg contacts of 3.4765(5) and 3.4013(1) ?. Wiberg indices of 0.12 are determined for these Rh???Hg interactions and an AIM analysis reveals bond paths with an electron density ρ(r) of 1.2×10?2 and 1.4×10?2 e/a03 at the bond critical points.

Optically active Lewis acids and Lewis pairs were synthesized and characterized by multinuclear NMR, UV/Vis spectroscopy and elemental analysis. Optical rotation measurements were carried out and the absolute configuration of the new chiral molecules conf
