5-Carboxy-2,4-dihydroxyanilinium chloride dihydrate
In the title compound, C(7)H(8)NO(4) (+)·Cl(-)·2H(2)O, the organic mol-ecule is almost planar with an r.m.s. deviation of 0.0164 Å for all non-H atoms. An S(6) ring motif is formed due to an intra-molecular O-H⋯O hydrogen bond. In the crystal, the mol-ecules are linked into a three-dimensional network by N-H⋯Cl, N-H⋯O, O-H⋯Cl and O-H⋯O hydrogen bonds.

In the title complex, [Cd(C(7)H(4)N(5)O(2))(2)(H(2)O)(2)]·2H(2)O, the water-coordinated Cd(II) atom ( symmetry) is coordinated by four N atoms from two symmetry-related 3-carboxy-pyidyl-6-tetra-zolato ligands, forming a distorted octa-hedral complex. The uncoordinated water mol-ecules connect the mononuclear units into a layer structure through O-H⋯N and O-H⋯O hydrogen bonds; similar hydrogen b...

The hydro-chloride salt of chiral l-nebivolol {systematic name: (+)-(R,S,S,S)-bis-[2-(6-fluoro-3,4-dihydro-2H-1-benzopyran-2-yl)-2-hydroxy-ethyl]ammonium chloride dihydrate}, C(22)H(26)F(2)NO(4) (+)·Cl(-)·2H(2)O, was obtained by chiral liquid chromatography as a dihydrate. The pyran rings adopt half-chair conformations. Hydrogen bonds between the cation, anions and water mol-ecules contribute t...
متن کامل8-Iodoquinolinium chloride dihydrate
The title compound, C(9)H(7)IN(+)·Cl(-)·2H(2)O, was obtained during the synthesis of 8-iodo-quinoline from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium ion is almost planar. Solvent water mol-ecules and chloride ions form a hydrogen-bonded chain along the c axis via O-H⋯Cl links. The 8-iodo-quinolinium ions, which are packed along the c axis with cationic aromatic π-π ...
متن کاملdl-Tyrosinium chloride dihydrate
In the title compound, C(9)H(12)NO(3) (+)·Cl(-)·2H(2)O, the cation has a protonated amino group resulting from proton transfer from chloridric acid. The structure displays double layers parallel to the [010] direction held together by N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds. These layers are stacked along the c axis at b = 1/2; within each layer, the tyrosinium cations are arranged in an...
