2-Ethyl-1H-imidazol-3-ium hemioxalate oxalic acid monohydrate.

ABSTRACT: In the title compound, C(5)H(9)N(2) (+)·0.5C(2)O(4) (2-)·C(2)H(2)O(4)·H(2)O, the anions, cations and water mol-eculars are linked by N-H?O and O-H?O hydrogen bonds which define a tightly bound three-dimensional structure. The title compound is a layered structure as viewed along the a or c axis; one layer contains water and oxalic acid mol-ecules, the other the imidazolium cation. The C atoms of the ethyl group of the 2-ethyl-imidazolium cation are disordered over two positions of equal occupancy.

Project description:In the title compound, C(8)H(13)N(2)O(2) (+)·Cl(-)·H(2)O, the methyl C atom of the ethyl group is slightly out of the imidazole plane, with an N-C(ring)-C-C torsion angle of -15.1 (2)°. In the crystal structure, there are strong inter-molecular hydrogen-bonding inter-actions between the solvent water mol-ecule, the free chloride anion and the organic cation, resulting in a two-dimensional supra-molecular network in the ab plane.

1-Ethyl-3-methyl-1H-imidazol-3-ium spiro-penta-borate.

Project description:In the anion of the title compound, (C6H11N2)[B5O6(OH)4], both six-membered borate rings adopt a flattened boat conformation with the spiro-B atom and its opposite O atom deviating from the remainders of the rings by 0.261 (3)/0.101 (2) and 0.160 (3)/0.109 (2) Å, respectively. The imidazolium cation also deviates from planarity due to rotation of the ethyl group (as indicated by the C-N-C-C torsion angle) by 71.4 (2)° out of the plane of the heterocycle. In the crystal, the anions are connected in a three-dimensional network through O-H⋯O hydrogen bonds, forming channels along the a-axis direction. The cations are situated in the channels, forming C-H⋯O hydrogen bonds with the anions.
