2-(2-Hydroxyphenyl)-4,5-dimethyl-1H-imidazol-3-ium acetate monohydrate
In the title compound, C(11)H(13)N(2)O(+)·C(2)H(3)O(2) (-)·H(2)O, 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.

The title merocyanine-type mol-ecule, C(21)H(22)N(2)O(5)·2H(2)O, crystallizes in a zwitterionic form and has an E configuration at the styryl C=C bond. The styryl part of the mol-ecule and the indolium ring are slightly twisted and form a dihedral angle of 13.4 (1)°. The 1.274 (3) Å C-O bond length in the phenolate fragment is the longest among similar mol-ecules. Hydrogen bonds between solvent...

In the crystal structure of the title compound, C(4)H(6)N(3) (+)·C(7)H(7)O(3)S(-), inter-molecular N-H⋯O hydrogen bonds link the cations and anions into chains along [100]. Additional stabilization is provided by weak C-H⋯O hydrogen bonds. An inter-molecular π-π stacking inter-action with a centroid-centroid distance of 3.6957 (7) Å is also observed. The H atoms of the methyl group were refined...

The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid ...

The title hydro-chloride salt, C(18)H(21)N(2)O(+)·Cl(-), is an imidazolidinone catalyst, which was derived from L-phenyl-alanine through cyclization with acetophenone. The imidazolidinone compound has a five-membered heterocyclic ring including two chiral centres. The imidazolidinone ring displays an envelope conformation, with the flap protonated N atom lying 0.497 (3) Å above the mean plane o...
