Crystal structure of 2-chloro-3-(dimethoxymethyl)-6-methoxyquinoline
The title compound, C13H14ClNO3, crystallizes with Z' = 2 in the space group Pca21, but a search for possible additional crystallographic symmetry found none. However, the crystal structure exhibits pseudosymmetry as the two independent mol-ecules are related by an approximate but non-crystallographic inversion located close to (0.38, 0.26, 1/2) in the selected asymmetric unit, and the structur...
متن کاملCrystal structure of ethyl 2-chloro-6-methylquinoline-3-carboxylate
In the title compound, C13H12ClNO2, the dihedral angle between the planes of the quinoline ring system (r.m.s. deviation = 0.029 Å) and the ester group is 54.97 (6)°. The C-O-C-Cm (m = meth-yl) torsion angle is -140.62 (16)°. In the crystal, mol-ecules inter-act via aromatic π-π stacking [shortest centroid-centroid separation = 3.6774 (9) Å] generating (010) sheets.
متن کاملCrystal structure of 3-bromomethyl-2-chloro-6-(dibromomethyl)quinoline
In the title compound, C11H7Br3ClN, the quinoline ring system is approximately planar (r.m.s. = 0.011 Å). In the crystal, mol-ecules are linked by C-H⋯Br inter-actions forming chains along [10-1]. The chains are linked by C-H⋯π and π-π inter-actions involving inversion-related pyridine rings [inter-centroid distance = 3.608 (4) Å], forming sheets parallel to (10-1). Within the sheets, there are...
متن کاملCrystal structure of 2-hydroxy-N-(2-hydroxyethyl)-N-{2-hydroxy-3-[(E)-N-hydroxyethanimidoyl]-5-methylbenzyl}ethanaminium acetate monohydrate
The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding in...
متن کاملCrystal structure of 2-(2,4-dichlorophenyl)-4-hydroxy-9-phenylsulfonyl-9H-carbazole-3-carbaldehyde
In the title compound, C25H15Cl2NO4S, the di-chloro-phenyl ring is twisted by 68.69 (11)° from the mean plane of the carbazole ring system [r.m.s. deviation = 0.084 (2)°]. The hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) graph-set motif. In the crystal, pairs of C-H⋯Cl hydrogen bonds link mol-ecules into inversion dimers with an R (2) 2(26) motif...
