A kryptoracemic salt: 2-{[2,8-bis(trifluoromethyl)quinolin-4-yl](hydroxy)methyl}piperidin-1-ium (+)-3,3,3-trifluoro-2-methoxy-2-phenylpropanoate
The asymmetric unit of the title salt, C17H17F6N2O(+)·C10H8F3O3 (-), comprises two piperidin-1-ium cations and two carboxyl-ate anions. The cations, each having an l-shaped conformation owing to the near orthogonal relationship between the quinolinyl and piperidin-1-ium residues, are pseudo-enanti-omeric. The anions have the same absolute configuration but differ in the relative orientations of...
متن کامل1-(4-Cyanophenyldiazen-2-ium-1-yl)-2-naphtholate
In the mol-ecule of the zwitterionic title compound, C(17)H(11)N(3)O, the naphthalene ring system is planar [maximum deviation = 0.029 (3) Å] and is oriented at a dihedral angle of 3.55 (3)° with respect to the benzene ring. An intra-molecular N-H⋯O hydrogen bond results in the formation of a planar six-membered ring. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ec...

In the title compound, C(7)H(8)N(3) (+)·C(10)H(6)F(3)O(2) (-), 1H-benzoimidazol-2-amine system adopts a planar conformation with an r.m.s. deviation of 0.0174 Å. The cation and anion in the asymmetric unit are linked by N-H⋯O hydrogen bonds. There are also additional inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions between the phenyl rings of neighbouring anions with centroid...

In the crystal structure of the title compound, C(19)H(20)FN(2)O(3) (+)·C(2)F(3)O(2) (-), N-H⋯O and O-H⋯O hydrogen bonds link two cations and two anions into a 22-atom ring. These rings are further linked into a three dimensional network by weak C-H⋯O contacts.
متن کامل2-Aminopyrimidin-1-ium 4-methylbenzenesulfonate
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...
