3,3′-Bis(4-nitro-phen-yl)-1,1′-(p-phenyl-ene)dithio-urea dimethyl sulfoxide disolvate

Abstract

The asymmetric unit of the title compound, C22H16N6O6S2·2C2H6OS, consists of one half-mol-ecule of the centrosymmetric thiourea derivative and one molecule of dimethyl sulfoxide (DMSO). The carbonyl group forms an intra-molecular hydrogen bond with the NH group, creating a six-membered (C - N - C - N - H⋯O) ring. Two other N - H⋯O hydro-gen bonds link one mol-ecule of the thio-urea to two mol-ecules of DMSO.
