title: (E)-3-(2-Chloro-6-methyl-3-quinol-yl)-1-(2,3-dihydro-1,4-benzodioxin-6-yl)prop-2-en-1-one.
abstract: In the title mol-ecule, C(21)H(16)ClNO(3), the quinoline and benzene rings are inclined at 56.96 (6)° with respect to each other and the dioxine ring is in a twist-chair conformation. The structure is devoid of any classical hydrogen bonds. Rather weak inter-molecular hydrogen-bonding inter-actions of the types C-H⋯N and C-H⋯O are present, consolidating the crystal structure.
