Crystal structure of 4-chloro-N-{[1-(4-chlorobenzoyl)piperidin-4-yl]methyl}benzamide monohydrate
In the title compound, C20H20Cl2N2O2·H2O, the piperidine ring adopts a chair conformation with the two substituent benzene rings inclined to one another [dihedral angle 84.63 (9)°]. In the crystal, the components are linked by Ow-H⋯O, N-H⋯Ow (w = water) and C-H⋯O hydrogen bonds, generating a sheet structure lying parallel to (101).

In the title compound, C22H27N2O2, the piperidine ring adopts a half-chair conformation with the benzene rings inclined in a trans orientation with respect to the piperidine ring [dihedral angle between the benzene rings = 89.1 (1)°]. In the crystal, a three-centre asymmetric N-H⋯O/C-H⋯O hydrogen-bonding inter-action leads to the formation of chains extending along the a-axis direction.
متن کاملCrystal structure of 3-methyl-2,6-bis(4-methyl-1,3-thiazol-5-yl)piperidin-4-one
In the title compound, C14H17N3OS2, the central piperidinone ring adopts a chair conformation and the thia-zole rings are inclined to its mean plane by 80.16 (12) and 67.15 (12)°. The O atom and methyl group C atom deviate significantly from the mean plane of the central piperidinone ring, by 0.8138 (2) and 0.3175 (2) Å, respectively. The dihedral angle between the thia-zole rings is 51.88 (13)...
متن کاملCrystal structure of 4-methyl-N-[2-(piperidin-1-yl)ethyl]benzamide monohydrate
In the title compound, C15H22N2O·H2O, the dihedral angle between the planes of the piperidine and benzene rings is 31.63 (1)°. The piperidine ring adopts a chair conformation. The water solvent mol-ecule is involved in inter-species O-H⋯O, O-H⋯N, N-H⋯O and weak C-H⋯O hydrogen-bonding inter-actions, giving rise to chains extending along [010].
متن کاملCrystal structure of 4-chloro-N-[2-(piperidin-1-yl)ethyl]benzamide monohydrate
In the title compound, C14H19ClN2O2·H2O, the piperdine ring adopts a chair conformation. The dihedral angle between the mean plane of the piperidine ring and that of the phenyl ring is 41.64 (1)°. In the crystal, mol-ecules are linked by O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds involving the water mol-ecule, forming double-stranded chains propagating along [010].
