Template synthesis of an intermediate in silver salt metathesis using a calix[4]arene-based diphosphine ligand

Abstract

The synthesis and solid-state characterisation of the heterobimetallic rhodium(III)/silver(I) complex [Rh(2,2′-biphenyl)(CxP₂)Cl]⊃Ag⁺ is described, where CxP₂ is a trans-spanning calix[4]arene-based diphosphine and the silver cation is datively bound to the chloride ligand within the cavity of the macrocycle.
