Abstract
In the title hydrated azo compound, C8H8N6S·H2O, the two aromatic groups are close to coplanar with the dihedral angle between the mean planes of the thia-zole and pyridine rings being 2.9 (2)°. The organic mol-ecule adopts an E configuration with respect to the double bond of the azo bridge. In the crystal, mol-ecules are linked by (amine)N-H⋯N(pyridine), (amine)N-H⋯O(water) and (water)O-H⋯N(thia-zole) hydrogen bonds along with π-π inter-actions involving pairs of thia-zole rings and pairs of pyridine rings. The plane-to-plane distance between two parallel mol-ecules is 3.7856 (4) Å and corresponds to the length of the a axis. In this way, a layer structure parallel to (010) is formed. The layers are linked by weak C-H⋯S hydrogen bonds, eventually resulting in a three-dimensional network.
