In the crystal, inter-molecular C-H?O inter-actions result in centrosymmetric head-to-head dimers with an R(2) (2)(14) graph-set motif along the b axis. Pairs of C-H?O and O-H?O hydrogen bonds form centrosymmetric head-to-head dimers about inversion centres, corresponding to an R(2) (2)(7) graph-set motif along the a axis.Acta crystallographica.
