2,4,6-Tri-tert-butyl-1,3,5-triphosphabenzene forms η 1 complexes with [AuL] +. Significant structural differences are observed between the P 3(C tBu) 3 units, depending on the auxiliary ligand bound to gold. For L = NHC, a planar P 3(C tBu) 3 is observed; for L = P( tBu) 2(o-biphenyl), the P 3(C tBu) 3 ligand is significantly puckered in the solid state. NICS computations on model complexes suggest this puckering only has a minor effect on the aromaticity of the heterocyclic ring.
