Abstract

The molecule of the title compound, C26H24N4O7S, adopts a trans conformation about the central N-N bond, presumably to minimize steric between the substituents on these two atoms. An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. The phenyl ring is disordered over two sets of sites, with an occupancy ratio of 0.624 (8):0.376 (8). The azolidine ring is essentially planar [maximum deviation = 0.008 (5) angstrom] and makes a dihedral angle of 4.3 (2)degrees with the benzene ring and dihedral angles of 74.1 (3) and 69.1 (5)degrees, respectively, with the mean planes of the major and minor components of the disordered phenyl ring. The packing in the crystal is aided by the formation of several weak C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions.
