چکیده
In the title compound, C(14)H(11)Cl(2)N(3)S, the thia-zole ring is in an envelope conformation with the -CH(2)- group bonded to the S atom forming the flap. The crystal structure is stabilized by weak inter-molecular C-H⋯Cl and C-H⋯N hydrogen bonds.

The mol-ecule 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 intra-molecular N-H⋯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...
