چکیده
The title Schiff base compound, C15H17N3O2S, is non-planar with a dihedral angle of 69.88 (4)° between the planes of the benzene rings. In the crystal, pairs of N-H⋯N hydrogen bonds, between the sulfonamide nitro-gen-H atom and the azomethine N atom, link the mol-ecules into inversion dimers, forming R 2 (2)(16) ring motifs. These dimers are linked by N-H⋯O hydrogen bonds, between the sulfonamide nitro-gen-H atom and one sulfonamide O atom, forming sheets lying parallel to (100). Within the sheets there are weak parallel slipped π-π inter-actions involving inversion-related benzene-sulfonamide rings [centroid-centroid distance = 3.8800 (9) Å; normal distance = 3.4796 (6) Å; slippage = 1.717 Å].

The title compound, C34H38ClN5O2, has spiro links connecting the pyrrolidine ring and indole residue, as well as the piperidine and pyrrolidine rings. A half-chair conformation is found for the piperidine ring with the C atom connected to the spiro-C atom lying 0.738 (4) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.0407 Å). The methyl-ene C atom is the flap in the envelo...
