Abstract We report the synthesis, structural characterisation andsolution‐phase dynamics of a series of polyaromatic hydrocarbon complexes of the 12‐electron {Rh(P i Bu 3 ) 2 } + fragment. Crystal structures of this fragment with benzene, naphthalene, anthracene, pyrene, triphenylene and coronene are described, alongside their solution NMR spectroscopic data. The ligands map out a systematic increase in size of the aromatic subunit, and represent an approach to the limiting case of coordination to a graphene surface. The solid‐state and solution structures of a {Rh(COD)} + fragment coordinated to a hexa‐ peri ‐hexabenzocoronene are also reported.
