We describe the synthesis of a ferrocenylene-bridged bis[2,5-bis(2-pyridyl)]phosphole ligand that shows additional rotational degrees of freedom relative to its previously described p-phenylene-bridged congener. The coordination behaviour of this ferrocenylene-based bis-N,P,N pincer towards coinage metal centres M-I with M = Cu and Au was explored, revealing different coordination modes with and without involvement of N donation. Upon coordination of Au-I metal centres, different isomers of a bimetallic Au-I complex were isolated in the crystalline solid state that showed (or did not) intramolecular aurophilic interaction. Aurophilic as well as Au-N interactions have been investigated by means of ab initio calculations.
