ABSTRACT

The title compounds, C17H13N3OS2, (I), and C17H12BrN3OS2, (II), are potential active pharmaceutical ingredients. Compound (I) comprises two almost planar fragments. The first is the central (carbamo­thio­yl)amide (r.m.s. deviation = 0.038 Å), and the second consists of the thia­zole and two phenyl rings (r.m.s. deviation = 0.053 Å). The dihedral angle between these planes is 15.17 (5)°. Unlike (I), compound (II) comprises three almost planar fragments. The first is the central N-(thia­zol-2-ylcarbamo­thio­yl)amide (r.m.s. deviation = 0.084 Å), and the two others comprise the bromo­phenyl and phenyl substituents, respectively. The dihedral angles between the central and two terminal planar fragments are 21.58 (7) and 17.90 (9)°, respectively. Both (I) and (II) feature an intra­molecular N—H⋯O hydrogen bond, which closes an S(6) ring. In the crystal of (I), mol­ecules form hydrogen-bonded layers parallel to (100) mediated by N—H⋯S and C—H⋯O hydrogen bonds. In the crystal of (II), mol­ecules form a three-dimensional framework mediated by N—H⋯Br and C—H⋯O hydrogen bonds, as well as secondary S⋯Br [3.3507 (11) Å] and S⋯S [3.4343 (14) Å] inter­actions.
