trans-3-(2-chloro-3-quinolyl)-1-phenyl-2,3-epoxypropan-1-one

In the title molecule, C18H12ClNO2, a quinolyl moiety is linked to a functionalized epoxide system in a trans configuration. The epoxide ring forms dihedral angles of 62.27 (2) and 79.82 (2)degrees with the 2-chloropyridine ring of the 2-chloro-quinolyl group and the phenyl ring, respectively. The mean plane of the atoms of the quinolyl ring system forms a dihedral angle of 35.03 (1)degrees with the phenyl ring. The crystal structure can be described as layers in which epoxide rings lie parallel to the (10(1) over bar) plane. The packing is stabilized by weak C-H center dot center dot center dot O and C-H center dot center dot center dot N intra- and intermolecular hydrogen bonds, resulting in the formation of a three-dimensional network.
