The seven-membered ring of the title compound, C(15)H(11)ClN(2)O(2), adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the methyl-ene C atom as the prow). The N atoms exists in a trigonal-planar coordination; one of the acetyl-enic H atoms forms a C-H⋯O hydrogen bond to the O atom of an adjacent mol-ecule, generating a linear chain along a body diagonal.
