The dihedral angle between the aromatic rings is 0.18 (14)°. There is a strong intramolecular O-H...O hydrogen bond. Geometrical parameters, determined using X-ray diffraction techniques, are compared with those calculated by density functional theory (DFT), using hybrid exchange-correlation functional, B3LYP and semi-empirical (PM3) methods.enSingle-crystal X-ray studyArticle10.1107/S16005368100034912-s2.0-77949416353WOS:000275126500134
