title: Crystal structure of (E)-2-[4-(4-hy-droxy-phen-yl)butan-2-yl-idene]hydrazine-1-carbo-thio-amide.
abstract: The title compound, C11H15N3OS, is a thio-semicarbazone derivative of the raspberry ketone rheosmin [systematic name: 4-(4-hy-droxy-phen-yl)butane-2-one]. The mol-ecule deviates from planarity, with the bridging C-C-C=N torsion angle equal to -101.3 (2)°. The maximum deviation from the mean plane of the non-H atoms of the thio-semicarbazone fragment [C=N-N-C(= S)-N] is 0.085 (5) Å for the Schiff base N atom, and the dihedral angle between this mean plane and the aromatic ring is 50.31 (8)°. In the crystal, mol-ecules are linked by N-H⋯O, N-H⋯S and O-H⋯S hydrogen bonds, forming a three-dimensional structure, with the mol-ecules stacked along [011].
