The reaction of [AuCl(tht)] (tht = tetrahydrothiophene) with an equimolar amount of the electron‐rich ligand N ‐diphenylphosphino‐triphenylphosphinimine, Ph 3 PNPPh 2 , in THF afforded the new complex [AuCl(Ph 3 PNPPh 2 )] ( 1 ) in good yield. Furthermore, the reaction of [AuHCl 4 ] with Ph 3 PNPPh 2 in a molar ratio of 1:3 in dichloromethane at room temperature yielded the complex salt [Au(Ph 3 PNPPh 2 ) 2 ]Cl ( 2 ) as the dichloromethane solvate beside Ph 3 PNPPh 2 Cl 2 as the side‐product of oxidation. The molecular structures of metal complexes 1 and 2 were determined by single‐crystal X‐ray diffraction. Because of the bulkiness of the ligand Ph 3 PNPPh 2 no short intermolecular gold–gold interactions (aurophilic aggregation) could be observed in the solid‐state structures.
