The benzhydryl compounds are a group of organic compounds whose parent structures include diphenylmethane (which is two benzene rings connected by a single methane), with any number of attached substituents, including bridges. This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes.
 The benzhydryl  radical  can be abbreviated Ph
2CH• or Bzh. [2] 
These species are not strictly benzhydryl-containing but are analogous.
