Benzhydryl compounds are compounds that are "diphenylmethane"-containing, i.e. two benzene rings adjoining a single carbon. This simple definition does not include heteroaromatic ring moieties, which would complicate the situation even further. Although it may still be desired to include these for the purposes of 'completeness' they ought to be kept separate to avoid confusion.
