In the title salt, C(9)H(20)NO(+)·ClO(4) (-), inter-molecular hydrogen bonds are observed, which determine the crystal packing.
In the crystal structure of the title compound, C(9)H(20)NO(+)·Cl(3)CCOO(-), the cations and anions are connected via O-H⋯O, N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonding. The six-membered ring adopts a chair conformation with the hydroxyl group in an equatorial position.
The crystal structure of the title compound, C(9)H(20)NO(+)·Cl(-)·0.33(H(3)O(+)·Cl(-)), is composed of 4-hydr-oxy-2,2,6,6-tetra-methyl-piperidinium cations, hydroxonium cations and chloride anions, which are connected via O-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonding. The 4-hydr-oxy-2,2,6,6-tetra-methyl-piperidinium cation and one of the two… (More)
In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)Cl(3)O(2) (-), the benzene ring forms an angle of 85.21 (13)° with the pyridinium ring. The nitro group is nearly coplanar with its attached benzene ring [dihedral angle = 3.68 (12)°]. In the crystal structure, strong N-H⋯O hydrogen bonds link the ion-pairs. The packing is further consolidated by weak C-H⋯O… (More)
