Crystal structure of 3-[2-(1,3-thia-zol-2-yl)diazen-1-yl]pyridine-2,6-di-amine monohydrate.

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.

2-(1,3-Thia-zol-4-yl)benzimidazolium nitrate monohydrate.

Project description:In the title compound, C(10)H(8)N(3)S(+)·NO(3) (-)·H(2)O, one of the N atoms of the benzimidazole unit is protonated, unlike than that in the thia-zole group. This protonation leads to equalization of the bond angles at the two N atoms of the benzimidazole group. The benzimidazole and thia-zole systems are almost coplanar, forming a dihedral angle of 0.5?(2)°. In the crystal, the nitrate anion and water mol-ecule bridge the thia-bendazolium cations through N-H?O and O-H?O hydrogen bonds, leading to a supra-molecular network based on an infinite one-dimensional chain using [001] as base vector.

Project description:The methyl-ene C atom in the title compound, C(13)H(16)N(2)S, is connected to a five-membered thia-zole ring and a mesityl substituent. The rings are aligned at 75.4 (1)°. The amino substitutent inter-acts with the ring N atom of an adjacent mol-ecule by an inter-molecular N-H⋯N hydrogen bond, generating a helical chain running along the b axis.
