چکیده
In the title compound C(17)H(25)NO(2), the piperidin-2-one ring adopts an envelope conformation with the C atom in the 5-position as the flap. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds, building a infinite chain along the b-axis direction. C-H⋯π inter-actions further stabilize the crystal packing.

Crystal structures of two chiral piperidine derivatives: 1-[(1R)-2-hydroxy-1-phenylethyl]piperidin-4-one and 8-[(1S)-1-phenylethyl]-1,4-dioxa-8-azaspiro[4.5]decane-7-thione
The crystal structures of the two title piperidine derivatives show different conformations for the six-membered heterocycle. The N-substituted 4-piperidinone 1-[(1R)-2-hy-droxy-1-phenyl-eth-yl]piperidin-4-one, C13H17NO2, (I), has a chair conformation, while the piperidine substituted in position 2 with a thio-carbonyl group, 8-[(1S)-1-phenyl-eth-yl]-1,4-dioxa-8-aza-spiro-[4.5]decane-7-thione, ...

The asymmetric unit of the title salt, C17H17F6N2O+·C8H7O3-·0.5H2O, comprises a pair of pseudo-enanti-omeric (i.e. related by a non-crystallographic centre of symmetry) piperidin-1-ium cations, two carboxyl-ate anions and a water mol-ecule of crystallization. The cations have similar conformations approximating to a letter, L: one of them shows disorder of its -CF3 group over two sets of sites ...

In the title compound, C(29)H(24)N(4)O(2)S, intra-molecular O-H⋯N hydrogen bonding influences the mol-ecular conform-ation; the naphthol system and triazole ring form a dihedral angle of 3.88 (7)°. In the crystal, π-π inter-actions between the five- and six-membered rings of neighbouring mol-ecules [centroid-centroid distances = 3.541 (3) and 3.711 (3) Å] consolidate the crystal packing.

The asymmetric unit of the title salt, C17H17F6N2O(+)·C10H8F3O3 (-), comprises two piperidin-1-ium cations and two carboxyl-ate anions. The cations, each having an l-shaped conformation owing to the near orthogonal relationship between the quinolinyl and piperidin-1-ium residues, are pseudo-enanti-omeric. The anions have the same absolute configuration but differ in the relative orientations of...
