Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.003 Å; R factor = 0.046; wR factor = 0.145; data-to-parameter ratio = 17.1. The title compound, C 21 H 14 O 6 S, is a new daidzein derivative with potential medical applications. The hydroxyphenyl ring makes a dihedral angle of 51.31 (8) with the benzopyranone ring. The crystal structure is stabilized by intermolecular O-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds.doi:10.1107/s1600536807057844 fatcat:sfdbfajlsfhdxb4vk34ky6i3ve
