RESUMO
In the cation of the title hydrated salt, C19H21N2O2S2 (+)·I(-)·H2O, the benzo-thia-zolium ring system is approximately planar [maximum deviation = 0.0251â (15)â Å], and it makes a small dihedral angle of 1.16â (18)° with the plane of the thio-phene ring. In the crystal, the cations, anions and crystalline water mol-ecules are linked by classical O-Hâ¯O, O-Hâ¯I and weak C-Hâ¯O hydrogn bonds, forming a three-dimensional supra-molecular network. π-π stacking is observed between parallel thia-zole rings of adjacent cations [centroid-centroid distance = 3.5945â (16)â Å].
RESUMO
In the title compound, C8H11NO2S, the aldehyde group is approximately coplanar with the thio-phene ring [maximum deviation = 0.023â (2)â Å]. In the crystal, mol-ecules are linked by O-Hâ¯O hydrogen bonds into supra-molecular chains propagating along the a-axis direction.
