[(L1)Au(μ-H)MCp][BF] complexes (M = Mo and W) featuring cavity-shaped tris-2-(4,4'-di--butylbi-phenylyl)phosphine (L1) have been isolated. The tungsten derivative showed a remarkably fast reactivity in photolytic hydride transfer to generate the mononuclear gold hydride (L1)AuH. Both bimetallic adducts trap Ag cations, forming unprecedented {Au(μ-H)M(μ-H)Ag} trimetallic assemblies with destabilized Au-M interactions.
