چکیده
In the title compound, C24H19N3O5S, the thia-zole ring (r.m.s. deviation = 0.012 Å) displays a planar geometry and is surrounded by three fragments, two meth-oxy-phenyl and one nitro-phenyl. The thia-zole ring is almost in the same plane as the nitro-phenyl ring, making a dihedral angle of 20.92 (6)°. The two meth-oxy-phenyl groups are perpendicular to the thia-zole ring [dihedral angles of 79.29 (6) and 71.31 (7)° and make a dihedral angle of 68.59 (7)°. The mol-ecule exists in an Z,Z conformation with respect to the C=N imine bond. In the crystal, a series of C-H⋯N, C-H⋯O and C-H⋯S hydrogen bonds, augmented by several π-π(ring) inter-actions, produce a three-dimensional architecture of mol-ecules stacked along the b-axis direction. The experimentally derived structure is compered with that calculated theoretically using DFT(B3YLP) methods.
