The title compound, C13H14NO2F3, crystallises with two mol-ecules, A and B, in the asymmetric unit, with similar conformations. The dihedral angles between the piperidine and phenyl rings are 83.76 (2) and 75.23 (2)° in mol-ecules A and B, respectively. The bond-angle sums around the N atoms [359.1 and 359.7° for mol-ecules A and B, respectively] indicate(More)
The title compound, C13H16ClNO2, crystallized with two independent mol-ecules in the asymmetric unit (A and B). The piperidinol ring in mol-ecule B is disordered over two positions with a site occupancy ratio of 0.667 (5):0.333 (5). In both mol-ecules these rings have a chair conformation, including the minor component in mol-ecule B. Their mean planes are(More)
In the title compound, 0.75C12H14ClNO2·0.25C12H14ClNO, which is an adduct comprising 0.75 4-hy-droxy-piperidin-1-yl or 0.25 4-piperidin-1-yl substituents on a common (4-chloro-phen-yl)methanone component; the dihedral angles between the benzene ring and the two piperidine rings are 51.6 (3) and 89.5 (7)°, respectively. The hy-droxy-piperidine ring is in a(More)
In the title compound, C13H17NO2, the dihedral angle between the planes of the piperidine and benzene rings is 51.7 (2)°. The bond-angle sum around the N atom [359.8 (3)°] indicates sp (2) hybridization of the atom. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules, forming chains along [001].
