چکیده
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 mol-ecules of DMSO.

In the title solvate, C44H30Cl2N2O2·2C4H8O2, the complete polycyclic mol-ecule is generated by inversion symmetry. The dihedral angle between the quinolyl ring system (Q; r.m.s. deviation = 0.020 Å) and the pendant phenyl ring is 78.80 (6)°; the dihedral angle between Q and the central benzene ring is 85.92 (7)°. In the crystal, the components are linked by C-H⋯O and C-H⋯π inter-actions, genera...
