چکیده
There are two structurally similar but crystallographically independent mol-ecules (A and B) in the asymmetric unit of the title compound, C(21)H(22)N(2)O(2), which are linked via two O-H⋯O hydrogen bonds. An intramolecular O-H⋯O hydrogen bond also occurs in each molecule. In the crystal, the A and B mol-ecules are further linked through C-H⋯O inter-actions. The benzene ring is twisted at an angle of 69.9 (1) and 83.4 (1)° relative to the 1,4-dihydro-quinoline skeleton in mol-ecules A and B, respectively. Adjacent 1,4-dihydro-quinoline units of mol-ecules A are parallel, while mol-ecules A and B are oriented at an angle of 32.8 (1)°.

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 ...

Two independent mol-ecules comprise the asymmetric unit of the title compound, C24H26N4O. The major difference between them is found in the relative orientation of the triazole-bound p-tolyl group which have the opposite sense of twist [N-N-C-C torsion angles = 55.8 (3) and -49.8 (3)°]. The chalcone residue is almost coplanar with the triazole ring [N-C-C-O and C-C-C-C torsion angles = -178.9 (...
