title: Ethyl 3-(2-chloro-5,8-dimeth-oxy-quinolin-3-yl)-2-cyano-oxirane-2-carboxyl-ate.
abstract: The title mol-ecule, C(17)H(15)ClN(2)O(5), contains a quinolyl unit linked to a functionalized oxirane system with a 2,3-trans arrangement of the substituents (ester group versus quinol-yl). The structure can be described as being built up from zigzag layers parallel to (1[Formula: see text]0). The heterocyclic ring of the quinolyl unit forms a dihedral angle of 60.05 (1)° with the oxirane plane. The crystal packing is stabilized by inter-molecular C-H⋯O and C-H⋯N hydrogen bonding, resulting in the formation of an infinite three-dimensional network and reinforcing the cohesion between the layers.
