Hitherto unknown Au→Al interactions have been evidenced upon coordination of the geminal phosphorus–aluminum Lewis pair Mes 2 PC(CHPh)Al t Bu 2 (Mes=2,4,6‐trimethylphenyl). Four different gold(I) complexes featuring alkyl (Me), aryl (Ph, C 6 F 5 ), and alkynyl (CCPh) co‐ligands have been prepared. X‐ray diffraction analyses show that P→Au→Al bridging coordination induces noticeable bending of the ligand (the PCAl bond angle shrinks by 13°). This new type of transition metal→Lewis acid interaction has been analyzed by DFT calculations.
