title: 4,4,4-Trifluoro-3-hy-droxy-3-(trifluoro-meth-yl)butanoic acid.
abstract: The asymmetric unit of the title compound, C(5)H(4)F(6)O(3), a polyfluorinated derivative of β-hy-droxy-butyric acid, comprises two mol-ecules. Intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, inter-molecular O-H⋯O hydrogen bonds give rise to the formation of carb-oxy-lic acid dimers. Along with these hydrogen bonds, C-H⋯O contacts connect the mol-ecules into infinite strands along the a axis.
