Project description:In the title compound, C23H20N3OS(+)·Br(-), the di-hydro-thia-zole ring (r.m.s. deviation = 0.015 Å) is twisted with respect to each of the C- and N-bound phenyl rings and the hy-droxy-benzene ring, making dihedral angles of 76.0 (2), 71.2 (2) and 9.8 (2)°, respectively. In the crystal, inversion-related mol-ecules are linked by association of the bromide ions with the cations via N-H⋯Br and O-H⋯Br hydrogen-bonding inter-actions. These mol-ecules run in channels parallel to the a axis through face-to-face π-π stacking inter-actions between the hy-droxy-benzene rings [centroid-centroid distances = 3.785 (3) Å] which, in turn, are connected into layers parallel to (110) by weak C-H⋯π inter-actions. A small region of electron density well removed from the main mol-ecule and appearing disordered over a center of symmetry was removed with PLATON SQUEEZE [Spek (2009 ▶). Acta Cryst. D65, 148-15] following unsuccessful attempts to model it as plausible solvent molecule. The nature of the solvent was not known and hence, this is not taken into account when calculating M r and related data.

Project description:In the title compound, C22H19N4S(+)·Br(-)·H2O, the dihedral angles between the phenyl groups and the mean plane of the thia-zolyl-idene ring are 34.69 (13) and 64.27 (13)°, respectively, while that between the thia-zolyl-idene and pyridinium rings is 14.73 (13)°. In the crystal, zigzag chains of alternating bromide ions and water mol-ecules associate through O-H⋯Br inter-actions run in channels approximately parallel to the b axis. These chains help form parallel chains of cations through N-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds.
