摘要

In the title hydrated azo compound, C8H8N6S#183;H2O, the two aromatic groups are close to coplanar with the dihedral angle between the mean planes of the thia#173;zole and pyridine rings being 2.9#8197;(2)#176;. The organic mol#173;ecule adopts an E configuration with respect to the double bond of the azo bridge. In the crystal, mol#173;ecules are linked by (amine)N#8212;H#8943;N(pyridine), (amine)N#8212;H#8943;O(water) and (water)O#8212;H#8943;N(thia#173;zole) hydrogen bonds along with #960;#8211;#960; inter#173;actions involving pairs of thia#173;zole rings and pairs of pyridine rings. The plane-to-plane distance between two parallel mol#173;ecules is 3.7856#8197;(4)#8197;#197; 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#8212;H#8943;S hydrogen bonds, eventually resulting in a three-dimensional network.
