The title compound [systematic name: 8-chloro-11-(piperidin-4-ylidene)-6,11-dihydro-5H-benzo[4,5]cyclohepta[2,1-b]pyridine], C19H19ClN2, was crystallized from ethyl acetate. The interesting feature of the reported structure is that it does not contain any strong hydrogen bonds, although the molecule contains a secondary NH group, which is a good hydrogen-bond donor.
