title: Crystal structure of methyl (2Z)-2-{[N-(2-formyl-phen-yl)-4-methyl-benzene-sulfonamido]-meth-yl}-3-(4-meth-oxy-phen-yl)prop-2-enoate.
abstract: In the title compound, C26H25NO6S, the S atom shows a distorted tetra-hedral geometry, with O-S-O [119.46 (9)°] and N-S-C [107.16 (7)°] angles deviating from ideal tetra-hedral values, a fact attributed to the Thorpe-Ingold effect. The sulfonyl-bound phenyl ring forms dihedral angles of 41.1 (1) and 83.3 (1)°, respectively, with the formyl-phenyl and phenyl rings. The dihedral angle between formyl-phenyl and phenyl rings is 47.6 (1)°. The crystal packing features C-H⋯O hydrogen-bond inter-actions.
