description

The crystal structures of the two title compounds display chair conformations of the piperidine rings in their mol­ecules. In compound (I), the biphenyl system has a twisted conformation with a dihedral angle of 26.57 (6)° while in compound (II) the two phenyl rings are exactly coplanar.
