Redetermination of {5-[(7-chloro-quinolinium-4-yl)amino]-2-hy-droxy-benz-yl}diethyl-ammonium dichloride dihydrate.

ABSTRACT: THE STRUCTURE OF THE TITLE COMPOUND (COMMON NAME: amodiaquinium dichloride dihydrate), C(20)H(24)ClN(3)O(2) (+)·2Cl(-)·2H(2)O, was previously determined from powder diffraction data [Llinàs et al. (2006 ▶). Acta Cryst. E62, o4196-o4199]. It has now been refined from diffractometer data to a significantly higher precision. The dihedral angle between the quinoline and benzene rings is 54.57 (6)°. The central amino N atom inter-acts more strongly with the quinoline ring than with the benzene ring, as indicated by the shorter C-N bond length [1.341 (2) Å compared to 1.431 (2) Å]. In the crystal, mol-ecules are packed into a three-dimensional network/supra-molecular structure through hydrogen bonds between the amodiaquinium cations, chloride anions and water mol-ecules.

Diethyl-ammonium 4-hy-droxy-benzoate.

Project description:In the crystal structure of the title compound, C(4)H(12)N(+)·C(7)H(5)O(3) (-), the cations and anions are linked by N-H⋯O and O-H⋯O hydrogen bonds, leading to the formation of a three-dimensional network.

Diethyl 2,2-bis-(3,5-di-tert-butyl-4-hy-droxy-benz-yl)malonate.

Project description:The title mol-ecule, C(37)H(56)O(6), possesses twofold symmetry, with the twofold axis passing through the quaternary C atom. In the crystal, neighbouring mol-ecules are linked via O-H?O hydrogen bonds involving the phenol OH group and the carbonyl O atom, forming chains propagating in [101]. Within these chains, rings are formed with an R(2) (2)(20) motif. There are also C-H?O inter-actions present within the rings.

Di-n-butyl-ammonium 2-[(3,5-di-tert-butyl-4-hy-droxy-benz-yl)sulfan-yl]benzoate.

Project description:The title salt, C(8)H(20)N(+)·C(22)H(27)O(3)S(-), is a proton-transfer compound derived from the recently reported parent carb-oxy-lic acid [Alhadi et al. (2010). Acta Cryst. E66, o1787] by the addition of a second equivalent of di-n-butyl-amine, yielding the di-n-butyl-ammonium carboxyl-ate salt. The structure of the carboxyl-ate anion resembles that of the parent carb-oxy-lic acid. The main difference lies in the position of the H atom in the 4-hy-droxy group. In the anion the O-H bond is perpendicular, rather than parallel, to the benzyl ring. This position appears to facilitate hydrogen bonding to an O atom of the carboxyl-ate group of a symmetry-related anion. In addition, there are three N-H⋯O hydrogen bonds. In contrast, the neutral species hydrogen bonds via a carboxylic acid dimer. The dihedral angle between the benzene rings in the anion is 79.19 (7)°.

N'-[(1E)-4-Diethyl-amino-2-hy-droxy-benz-idene]benzohydrazide.

Project description:In the title compound, C(18)H(21)N(3)O(2), the dihedral angle between the phenyl and benzene rings is 36.85 (10)°. The methyl C atom of one of the ethyl groups is disordered over two positions with site occupancies of 0.810 (8) and 0.190 (8). The mol-ecular structure is stabilized by a classical intra-molecular O-H⋯N hydrogen bond. The crystal structure exhibits weak inter-molecular N-H⋯O, C-H⋯O and C-H⋯π inter-actions.

Project description:The title molecular salt, C(11)H(17)ClNO(+)·C(7)H(5)O(3) (-), was obtained by the reaction of racemic clorprenaline and 4-hy-droxy-benzoic acid. In the crystal, the components are connected by O-H?O and N-H?O hydrogen bonds, resulting in a two-dimensional hydrogen-bonded network.

Bis(2-hy-droxy-eth-yl)ammonium picrate.

Project description:The asymmetric unit of the title salt, C4H12NO2 (+)·C6H2N3O7 (-), contain two bis-(2-hy-droxy-eth-yl)ammonium cations and two picrate anions. An intra-molecular N-H?O hydrogen bond occurs in each cation. In the crystal, mol-ecules are linked via O-H?O and N-H?O hydrogen bonds, which generate two R 2 (1)(6), an R 2 (2)(10) and an R 2 (2)(13) graph-set ring motifs. There are also a number of C-H?O hydrogen bonds present. The sum of these inter-actions leads to the formation a three-dimensional structure.

4-[(2-Hy-droxy-benz-yl)amino]-pyridinium nitrate.

Project description:The planes of the aromatic rings in the cation of the title salt, C(12)H(13)N(2)O(+)·NO(3) (-), are twisted along the -CH(2)-NH- single bond by 75.3 (1)°. In the crystal, the phenol O, amine N and pyridinium N atoms are hydrogen-bond donors to the O atoms of the nitrate counter-ions. These hydrogen bonds lead to the formation of a layer in the crystal.

Crystal structure of 3-[({2-[bis-(2-hy-droxy-benz-yl)amino]-eth-yl}(2-hy-droxy-benz-yl)amino)-meth-yl]-2-hydroxy-5-methyl-benzaldehyde.

Project description:The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by hydrogen bonds. In the 2-hy-droxy-5-methyl-benzaldehyde group, an intra-molecular S(6) O-H?O hydrogen bond is observed between the alcohol and aldehyde functions, and the neighbouring phenol arm participates in an intra-molecular S(6) O-H?N hydrogen bond. The third phenol group is involved in a bifurcated intra-molecular hydrogen bond with graph-set notation S(6) for O-H?N and O-H?O intra-molecular hydrogen bonds between neighbouring amine and phenol arms, respectively. Finally, the fourth phenol group acts as an acceptor in a bifurcated intra-molecular hydrogen bond and also acts as donor in an inter-molecular hydrogen bond, which connects inversion-related mol-ecules into dimers with R 4 (4)(8) ring motifs.

Tetra-butyl-ammonium 4-hy-droxy-benzoate dihydrate.

Project description:In the title compound, (n-C(4)H(9))(4)N(+)·C(7)H(5)O(3) (-)·2H(2)O, the carboxyl-ate group is twisted slightly out of the plane of the attached benzene ring, the two C-C-C-O torsion angles being -8.9?(2) and -10.7?(2)°. The anion inter-acts with two water mol-ecules through several O-H?O hydrogen bonds, forming wide ribbons along the a axis constructed from two anion-water chains. These ribbons are contained between unclosed diamond-like (16.2 × 15.0?Å) channels constructed by four rows of tetra-butyl-ammonium cations, which are arranged along the [011] and [01[Formula: see text]] directions.
