In the mol-ecular structure of the title compound, C(13)H(12)N(2)O(4)S(2), there is a dihedral angle of 0.41 (13)° between the benzene and thia-zole rings. In the crystal, inversion dimers linked by two C-H⋯O inter-actions together with π-π stacking between the parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.673 (2) Å].
In the title compound, C(26)H(25)ClN(4)O(3)S, the acyclic imine group exhibits an E configuration. The triazole ring is oriented at dihedral angles of 53.84 (2), 70.77 (1) and 32.59 (3)° with respect to the benzene rings of the 2-chloro-benzyl-idene, 4-methyl-benzyl-sulfanyl and 3,4,5-trimethoxy-phenyl groups, respectively. The crystal packing is stabilized(More)
The title compound, C(22)H(24)N(4)O(4)S, adopts a trans configuration with respect to the C=N double bond. A weak intra-molecular C-H⋯N hydrogen bond is observed between the N atom of the C=N double bond and its neighboring phenyl H atom. The crystal structure is stabilized by inter-molecular C-H⋯N hydrogen bonds and C-H⋯π inter-actions.
