title: Crystal structure of (4-hy-droxy-piperidin-1-yl)[4-(tri-fluoro-meth-yl)phen-yl]methanone.
abstract: 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 sp (2) hybridization for these atoms. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into separate [100] chains of A and B mol-ecules. The chains are cross-linked by C-H⋯O inter-actions, generating alternating (001) sheets of A and B mol-ecules.
