Crystal structure of (E)-2-[4-(4-hydroxyphenyl)butan-2-ylidene]hydrazine-1-carbothioamide

What is it about?

The title compound, C11H15N3OS, is a thio­semicarbazone derivative of the raspberry ketone rheosmin [systematic name: 4-(4-hy­droxy­phen­yl)butane-2-one]. The mol­ecule 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 thio­semicarbazone 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, mol­ecules are linked by N-H...O, N-H...S and O-H...S hydrogen bonds, forming a three-dimensional structure, with the mol­ecules stacked along [011].
