Research output: Contribution to journalArticlepeer-review


In crystals of the title compound, C23H23N5O3S, the indole system is planar and the phenyl ring of the phenylsulfonyl group makes a dihedral angle with the best plane of the indole system of 77.18 (4)°. The olefinic bond connecting the aza-bicyclic and indole systems has Z geometry. The geometry adopted by the C=O bond with respect to the N - N bond is trans. The O atom of the carbonyl group of each mol-ecule is hydrogen bonded to the hydrazidic H atom of an adjacent mol-ecule to form an eight-membered-ring dimeric structure.
