organic compounds
In the title compound, C24H27N3O2S·C2H6O, the dihedral angle between the least-squares planes of the 2,5-dihydroxybenzene ring and the mesityl group is 78.59 (6)°. An intramolecular O—HN hydrogen bond is observed in the molecular structure. Centrosymmetrically related molecules are linked by N—HO intermolecular hydrogen bonds to form a dimer. The dimers are interlinked by O—HO and O—HN intermolecular hydrogen bonds involving the ethanol molecule of crystallization to form chains along the a axis.
organic compounds
The structure of the title compound, C38H56N8S2·2C2H6OS, has been determined by single-crystal diffractometry and is compared with the structures of other compounds containing the thiosemicarbazide group. The structure is stabilized by N—HS hydrogen bonding, resulting in the formation of infinite chains parallel to the [010] axis. The thiosemicarbazone group has an E configuration.
