Bis(5-phenyl-1H-1,2,4-triazol-3-yl) disulfide dihydrate.

ABSTRACT: A crystallographic twofold axis passing through the centre of the disulfide linkage in the title compound, C(16)H(12)N(6)S(2)·2H(2)O, results in one-half of the mol-ecule and one uncoordinated water mol-ecule described in the asymmetric unit. In the mol-ecule, the mean planes of the benzene and triazole rings are close to being coplanar and are separated by a dihedral angle of 2.08 (15)°. The triazole rings are twisted by a dihedral angle of 37.67 (6)° from the disulfide linkage. The crystal packing is stabilized by inter-molecular N-H⋯O and O-H⋯N hydrogen bonds with the water mol-ecules, forming a three-dimensional supra-molecular network.

3-Phenyl-1H-1,2,4-triazol-5-amine-5-phenyl-1H-1,2,4-triazol-3-amine (1/1).

Project description:In the title compound, C(8)H(8)N(4)·C(8)H(8)N(4), two tautomers, viz. 3-phenyl-1,2,4-triazol-5-amine and 5-phenyl-1,2,4-triazol-3-amine, are crystallized together in equal amounts. The 3-phenyl-1,2,4-triazol-5-amine mol-ecule is essentially planar; the phenyl ring makes a dihedral angle of 2.3 (2)° with the mean plane of the 1,2,4-triazole ring. In the 5-phenyl-1,2,4-triazol-3-amine tautomer, the mean planes of the phenyl and 1,2,4-triazole rings form a dihedral angle of 30.8 (2)°.

Adjacent units are inter-connected though O-H⋯N hydrogen bonds, forming a three-dimensional network.

1-{4-[(1H-1,2,4-Triazol-1-yl)meth-yl]benz-yl}-1H-1,2,4-triazol-4-ium perchlorate.

Project description:In the crystal structure of the title compound, C(12)H(13)N(6) (+)·ClO(4) (-), the cation, located about an inversion center, is monoprotonated, and one H atom is disordered over two sites on N atoms of the two triazole rings, each with an occupancy factor of 0.5. The perchlorate anion has C(2) symmetry, the Cl atom and one O atom lying on the twofold rotation axis; the anion is thus disordered over two sites of equal occupancy. In the cation, the triazole ring makes a dihedral angle of 84.75 (7)° with the plane of the benzene ring. In the crystal, inter-molecular N-H⋯N hydrogen bonding between the triazole and triazolium rings links the cations into a wave-like supra-molecular chain. Weak inter-molecular C-H⋯N and C-H⋯O hydrogen bonding is also present.
