چکیده
The title compound, C(26)H(24)N(2)O(3), was synthesized by reduction of the corresponding Schiff base. The mol-ecule does not possess crystallographic or non-crystallographic symmetry. The dihedral angle between the oxygen-bridged benzene rings is 67.98 (8)°. Both hydroxyl groups are involved in O-H⋯O intra-molecular hydrogen bonding. The mol-ecules are linked into a two-dimensional network parallel to the (010) plane by N-H⋯O hydrogen bonds.

In the title compound, C(11)H(13)BrOS, the thio-ether unit and the phenyl ring adopt an essentially planar conformation, with a maximum deviation of 0.063 Å. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, extending in zigzag chains along the b axis. A weak intra-molecular C-H⋯Br hydrogen bond is also observed, which forms an S(6) ring motif.
