Abstract
Tris(2-cyanoethyl)phosphine (CEP) acts as a phosphorus-donor ligand forming strong metal-phosphorus bonds in several metal complexes. It forms monomeric complexes with AuCl and AuBr, whereas an ionic complex [{(CEP) 2Au} +{Au(CN) 2} −] ( I) was formed with AuCN, presumably as a result of ligand scrambling in solution. The X-ray structure of I revealed mutually perpendicular [(CEP)Au(CEP) + and [(CN)Au(CN)] − ions, with an AuAu separation of 3.279(2) Å. No inter- or intramolecular metal coordination of CN groups was observed. There are two three-coordinated gold atoms per asymmetric unit, with a packing pattern based upon alternating [(CEP) 2Au] + and [Au(CN) 2] − ions. The presence of CN groups in gold complexes of trialkylphosphines appears to be conductive towards ligand scrambling reactions forming ionic complexes, as compared to the monomeric linear species in the case of chloro or bromo complexes.
