Accepted 27 July 2016

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.

Accepted 27 July 2016

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.

Accepted 26 July 2016

Crystal structure of methyl (E)-4-[2-(8-hy­droxy­quinolin-2-yl)vin­yl]benzoate

The title 8-hy­droxy­quinoline derivative has an E conformation about the C=C bond, and the quinoline ring system and the benzene ring are inclined to one another by 29.22 (7)°.
