چکیده
The asymmetric unit of the title compound, C(6)H(8)N(+)·HSO(4) (-), contains two cations and two anions which are linked to each other through N-H⋯O hydrogen bonds, formed by all H atoms covalently bonded to the N atoms. In addition, strong O-H⋯O anion-anion hydrogen-bond inter-actions are also observed.

In the title compound, 2C(6)H(9)BNO(2) (+)·SO(4) (2-), the dihydroxy-boryl group of one of the two independent boronic acid mol-ecules participates in (B)O-H⋯O(B) and N-H⋯O(B) hydrogen bonds, while the second is involved mainly in the formation of the charge-assisted heterodimeric synthon -B(OH)(2)⋯(-)O(2)SO(2) (-). These aggregates are further connected through N-H⋯O(sulfate) inter-actions, fo...

The asymmetric unit of the title compound, 2C20H22N3O3(+)·SO4(2-)·H2O, contains four cations, two sulfate anions and two lattice water mol-ecules. One of the four cations shows a different conformation of the hy-droxy-ethyl group; the remaining three are all essentially superimposable. Two cations exhibit two-site orientational disorder [ratios = 0.524 (5):0.476 (5) and 0.616 (6):0.384 (6)] of ...
متن کاملPhenyl-ring rotational disorder in the two-dimensional hydrogen-bonded structure of the 1:1 proton-transfer salt of the diazo-dye precursor 4-(phenyldiazenyl)aniline (aniline yellow) with L-tartaric acid.
In the structure of the 1:1 proton-transfer compound from the reaction of L-tartaric acid with the azo-dye precursor aniline yellow [4-(phenyldiazenyl)aniline], namely 4-(phenyldiazenyl)anilinium (2R,3R)-3-carboxy-2,3-dihydroxypropanoate, C(12)H(12)N(3)(+) x C(4)H(5)O(6)(-), the asymmetric unit contains two independent 4-(phenyldiazenyl)anilinium cations and two hydrogen L-tartrate anions. The ...
متن کاملAnilinium 3,4-dihydroxybenzoate
The asymmetric unit of the title salt, C(6)H(8)N(+)·C(7)H(5)O(4) (-), contains two anilinium cations and two 3,4-dihy-droxy-benzoate anions. An intra-moleculer O-H⋯O hydrogen bond occurs in each anion. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the cations and anions into a three-dimensional array. The structure is further consolidated by weak C-H⋯O inter-actions.

The crystal structure of the high temperature phase of anilinium bromide, CeH5NH3®Br , was studied by X-ray and neutron diffraction at T = 343 K . The refinement supports disordered positions of the —NH3® group. A split-atom model is proposed which includes disorder of the benzene ring. The thermal parameters, hydrogen bond distances, and other experimental data (NMR, N Q R , inelastic neutron ...
