Abstract:
The asymmetric unit of the title compound, C(8)H(6)N(8)·2H(2)O, contains one half-mol-ecule, with the benzene ring on a centre of symmetry, and two uncoordinated water mol-ecules. The benzene ring is oriented at a dihedral angle of 34.43 (12)° with respect to the tetra-zole ring. Strong O-H⋯N hydrogen bonds link the water mol-ecules to the N atoms of the tetra-zole ring. In the crystal structure, strong inter-molecular O-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules into a network. One of the water H atoms is disordered over two positions and was refined with occupancies of 0.50.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
