8-(2,2,2-Trifluoro-ethoxy)quinolinium perchlorate-8-(2,2,2-trifluoro-ethoxy)quinoline (1/1).

ABSTRACT: The title compound, C(11)H(9)F(3)NO(+)·ClO(4) (-)·C(11)H(8)F(3)NO or [(C(11)H(8)F(3)NO)H(C(11)H(8)F(3)NO)]ClO(4), contains two 8-(2,2,2-trifluoro-eth--oxy)quinoline molecules, one of which combines a proton from perchloric acid to form the corresponding quinolinium cation. The quinolinium and quinoline rings form a cationic unit via an inter-molecular N-H⋯N hydrogen bond. The heterocyclic units are almost perpendicular to each other [inter-planar angle 86.97 (6)°]. In the crystal, each perchlorate anion bridges two adjacent cationic units and creates a chain by a combination of C-H⋯O hydrogen bonds. Two inversion-related chains associate into a mol-ecular column by π-π stacking inter-actions between the quinolinium rings. The perpendicular and centroid-centroid distances between adjacent q
