Di­bromido­bis­(2-methyl-1H-benzimidazole-κN³)cadmium

In the title compound, [CdBr₂(C₈H₈N₂)₂], the Cd^II atom has a distorted tetra­hedral coordination formed by the two imino N atoms of two 2-methyl­benzimidazole ligands and two terminal bromide ligands. The Cd^II atom is slightly out of the benzimidazole planes by 0.320 (3) and 0.210 (3) Å. The dihedral angle between the benzimidazole planes is 71.6 (2)°. In the crystal, mol­ecules are linked by N—H...Br hydrogen bonds into puckered layers parallel to (001).

5,6-Dimethyl-1H-benzimidazol-3-ium nitrate

The title salt, C₉H₁₁N₂⁺·NO₃⁻, features a planar cation (r.m.s. for 11 non-H atoms = 0.016 Å). In the crystal, N—H...O hydrogen bonds link nitrate and benzimidazole ions into a three-dimensional network.
