Crystal structure of 1-(5-bromo-1-benzofuran-2-yl)ethanone oxime
The title compound, C10H8BrNO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and the conformation across the C=N bond is trans. Further, the O atom of the benzo-furan ring is syn to the N atom of the oxime group. In the crystal, inversion dimers linked by pairs of O-H⋯N hydrogen bonds generate R 2 (2)(6) loops. Very weak aromatic π-π stacking inter-actions [centroid-centroi...

In the title compound, C(20)H(21)N(3)O(2)·H(2)O, the aza-substitued six-membered ring adopts a (L4)B conformation. In the crystal, classical N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the entities into a three-dimensional network. Intra-molecular C-H⋯O contacts are also observed.

The 1,4-dihydro-pyridine ring in the title hydrate, C(17)H(18)BrNO(2)·H(2)O, has a flattened-boat conformation, and the benzene ring is occupies a position orthogonal to this [dihedral angle: 82.19 (16)°]. In the crystal packing, supra-molecular arrays mediated by N-H⋯O(water) and O(water)-H⋯O(carbon-yl) hydrogen bonding are formed in the bc plane. A highly disordered solvent mol-ecule is prese...
متن کامل1-(5-Acetyl-2-hydroxyphenyl)ethanone
The crystal structure of the title compound, C(10)H(10)O(3), is characterized by classical intra-molecular hydrogen bonding. The hy-droxy group is disordered over two positions (77 and 23%). The crystal structure is stabilized via π-π [3.5986 (1) Å] and weak nonclassical C-H⋯O inter-actions [3.2797 (15) Å].
متن کامل2-Chloro-1-(3,3-dimethyl-2,6-diphenylpiperidin-1-yl)ethanone
In the title compound, C21H24ClNO, the piperidine ring adopts a chair conformation. The two phenyl rings are inclined to one another by 20.7 (1)°, and are inclined to the mean plane of the four planar atoms of the piperidine ring by 87.64 (10) and 70.8 (1)°. The mol-ecular structure features short intra-molecular C-H⋯Cl and C-H⋯O contacts. In the crystal, there are no significant inter-molecula...
