Crystal structure of (E)-2-(4-chloro­benzyl­idene)-3,4-di­hydro­naphthalen-1(2H)-one: a second monoclinic polymorph

The title compound, C(17)H(13)ClO, is the second monoclinic polymorph to crystallize in the space group P2(1)/c. The first polymorph crystallized with two independent mol­ecules in the asymmetric unit [Bolognesi et al. (1975 ▸). Acta Cryst. A31, S119; Z′ = 2; no atomic coordinates available], wherea...

description The title compound, C(17)H(13)ClO, is the second monoclinic polymorph to crystallize in the space group P2(1)/c. The first polymorph crystallized with two independent mol­ecules in the asymmetric unit [Bolognesi et al. (1975 ▸). Acta Cryst. A31, S119; Z′ = 2; no atomic coordinates available], whereas the title compound has Z′ = 1. In the title polymorph, the dihedral angle between the plane of the benzene ring of the tetra­lone moiety and that of the 4-chloro­benzyl ring is 52.21 (11)°. The cyclo­hex-2-en-1-one ring of the tetra­lone moiety has a screw-boat conformation. In the crystal, mol­ecules are liked by pairs of C—H⋯π inter­actions forming inversion dimers. There are no other significant inter­molecular inter­actions present.
