Abstract:
In the cation of the title compound, C(6)H(6)N(5) (+)·Cl(-), the tetra-zole and pyridine rings are nearly coplanar, making a dihedral angle of 5.58 (11)°. The organic cations are linked to the chloride anions via N-H⋯Cl hydrogen bonds, forming chains along [110].

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
