title: 7-Chloro-3,3-dimethyl-9-phenyl-1,2,3,4-tetra-hydro-acridin-1-one.
abstract: In the title salt, C(21)H(18)ClNO, the quinoline ring system is approximately planar [maximum deviation = 0.035 (2) Å], and forms a dihedral angle of 71.42 (6)° with the attached phenyl ring. The cyclo-hexa-none ring exists in a half-boat conformation. In the crystal packing, C-H⋯O contacts link the mol-ecules into extended supra-molecular chains along the c axis.
