2-Methyl-5-nitro-1H-benzimidazol-6-amine dihydrate
Abstract:
The title benzimidazole mol-ecule, C(8)H(8)N(4)O(2)·2H(2)O, is planar with a maximum deviation of 0.079 (2) Å (for one of the O atoms in the nitro group). It crystallized as a dihydrate and inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the uncoordinated water mol-ecules, and the nitro and amine groups, respectively. In the crystal, N-H⋯O, O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules to form a three-dimensional network. A π-π contact between the benzene rings, [centroid-centroid distance = 3.588 (1) Å] may further stabilize the crystal structure.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
