چکیده
In the title salt, C9H8N3O2(+)·Cl(-), the least-squares planes of the imidazolium and benzene rings are almost coplanar, making a dihedral angle of 4.59 (1)°. In the crystal, the chloride anion links the organic mol-ecules through N-H⋯Cl hydrogen bonds, forming chains that run diagonally across the bc face, which compliment strong C-H⋯O hydrogen bonds between neighbouring mol-ecules. These chains are connected to adjacent chains through two weak C-H⋯Cl inter-actions, resulting in hydrogen-bonded sheets extending along the b and c axes. The absolute structure of the title compound was determined using a Flack x parameter of 0.00 (6) and a Hooft y parameter of 0.03 (2).

In the cation of the title compound, C(21)H(16)N(3)O(2) (+)·Cl(-), the N atom in the 3-position of the imidazole ring is protonated. The three pendant aromatic rings are twisted from the plane of the imidazolium ring by dihedral angles of 31.69 (14)°, 31.09 (14)° and 34.77 (14)°. In the crystal structure, N-H⋯Cl hydrogen bonds link the mol-ecules, forming a chain parallel to the b axis.
