Abstract:
In the title hydrated azo dye, C10H10N4OS·H2O, the benzene and thia-zole, are nearly coplanar, with a dihedral angle between their mean planes of 4.69 (17)°. The aromatic rings on the -N=N- moiety exhibit a trans configuration. The crystal structure features many types of inter-molecular inter-actions involving all the functional groups - strong hydrogen bonds (N⋯H and O⋯H), weak hydrogen bonds (C-H⋯O and C-H⋯N), C-H⋯π and π-π inter-actions - resulting in the formation of a three-dimensional framework.

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
