چکیده
The asymmetric unit of the title solvate, C(20)H(14)O(4)·2C(2)D(6)OS, contains half of the substituted terephthalic acid mol-ecule and one solvent mol-ecule. The centroid of the central benzene ring in the acid mol-ecule is coincident with a crystallographic inversion center. Neither the carboxyl nor the phenyl substituents are coplanar with the central aromatic ring, showing dihedral angles of 53.18 (11) and 47.83 (11)°, respectively. The dimethyl sulfoxide solvent mol-ecules are hydrogen bonded to the carb-oxy-lic acid groups.

The asymmetric unit of the title compound, C(22)H(16)N(6)O(6)S(2)·2C(2)H(6)OS, 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 m...
