Dimethyl (2Z)-2-[4-((1Z)-1-{2-[(2Z,5Z)-5-(2-meth-oxy-2-oxo-ethyl-idene)-4-oxo-3-phenyl-1,3-thia-zolidin-2-yl-idene]hydra-zin-1-yl-idene}eth-yl)anilino]but-2-ene-dio-ate.

ABSTRACT: 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?(5)?Å] and makes a dihedral angle of 4.3?(2)° with the benzene ring and dihedral angles of 74.1?(3) and 69.1?(5)°, 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?O and C-H?N inter-actions.
