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


The title compound, C17H13ClO, is the second monoclinic polymorph to crystallize in the space group P21/c. The first polymorph crystallized with two independent mol-ecules 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… (More)
