Crystal structure of dimethylformamidium bis(trifluoromethanesulfonyl)amide: an ionic liquid
The cation and anion of the title salt are linked by an O—H⋯N hydrogen bond and a C—H⋯O interaction, resulting in a high viscosity and a crystallization temperature slightly lower than ambient temperature.
Crystal structure of 1-amino-2-oxo-2,5,6,7,8,9-hexahydro-1H-cyclohepta[b]pyridine-3-carbonitrile
In the title compound the seven-membered ring adopts a conformation such that the three atoms not involved in the aromatic plane lie on the same side of that plane. One hydrazinic H atom forms an intramolecular hydrogen bond to the O atom; the other forms a classical intermolecular hydrogen bond N—H⋯O, which combines with a `weak' Har⋯O interaction to build up double layers of molecules parallel to the bc plane.
