4-Carb­oxy-2-methyl-1H-imidazol-3-ium-5-carboxyl­ate monohydrate

In the title compound, C6H6N2O4·H2O, one carboxyl group is deprotonated and one imidazole N atom is protonated. The organic mol­ecule, excluding methyl H atoms, is essentially planar, with an r.m.s. deviation of 0.0156 (1) Å. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link mol­ecules into chains along the b axis; these chains are further linked via O—H⋯O hydrogen bonds involving the water O atoms and carboxyl O atoms, generating a two-dimensional supra­molecular framework

2-(2-Hydroxyphenyl)-4,5-dimethyl-1H-imidazol-3-ium acetate monohydrate

In the title compound, C11H13N2O+·C2H3O2 −·H2O, the dihedral angle between the benzene ring and the imidazole ring is 7.83 (6)°. In the crystal structure, N—H⋯O and O—H⋯O hydrogen bonds form a two-dimensional network. All the methyl H atoms are disorderd over two sites with equal occupancies

2-(4-Fluoro­phen­yl)-1-(4-meth­oxy­phen­yl)-4,5-dimethyl-1H-imidazole

In the title compound, C18H17FN2O, the imidazole ring makes dihedral angles of 76.46 (7) and 40.68 (7)° with the meth­oxy­phenyl and fluoro­phenyl rings, respectively. The dihedral angle between the two benzene rings is 71.25 (6)°

Antimicrobial activities of the compounds are examined and notable antifungal activity is obtained from some of the compounds as expected in comparison with the control agent ketoconazole

4-(4,5-Diphenyl-1H-imidazol-2-yl)-N,N-dimethylaniline

The asymmetric unit of the title compound, C23H21N3, consists of two symmetry-independent and conformationally different molecules [the comparable dihedral angles between the imidazole ring and the three benzene rings being 38.5 (2)/61.5 (3)/3.37 (17) and 45.8 (2)/36.01 (19)/46.94 (17)°]. In the crystal, intermolecular imidazole N—H...N hydrogen-bonding interactions give a one-dimensional chain extending along [101]
