Dimethyl 3,3'-diphenyl-2,2'-[(S)-thio-phene-2,5-diylbis(carbonyl-aza-nedi-yl)]dipropano-ate.

ABSTRACT: The asymmetric unit of the title compound, C(26)H(26)N(2)O(6)S, contains two independent mol-ecules; each has twofold symmetry with the S atom and the mid-point of the C-C bond of the thio-phene ring located on a twofold rotation axis. In the two mol-ecules, the terminal benzene rings are oriented at dihedral angles of 65.8 (3) and 63.5 (3)° with respect to the central thio-phene rings. The meth-oxy-carbonyl group of one mol-ecule is disordered over two positions with site-occupancy factors of 0.277 (12) and 0.723 (12). Inter-molecular N-H⋯O hydrogen bonding is present in the crystal structure.
