Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Hitherto unknown Au→Al interactions have been evidenced upon coordination of the geminal phosphorus–aluminum Lewis pair Mes₂PC(CHPh)Al<italic>t</italic>Bu₂ (Mes=2, 4, 6‐trimethylphenyl). Four different gold(I) complexes featuring alkyl (Me), aryl (Ph, C₆F₅), and alkynyl (CCPh) 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.</p> </abstract>
