Abstract:
In the crystal of the title compound, C(17)H(15)N(3)S(2)·0.5C(2)H(6)O, the mol-ecules are linked by a pair of N-H(aliphatic)⋯S hydrogen bonds across a center of inversion, forming a dimer. The ethanol solvent mol-ecule, which is statistically disordered about a crystallographic twofold rotation axis, accepts an N-H(aromatic)⋯O hydrogen bond; the hydr-oxy group of the solvent mol-ecule is not engaged in hydrogen bonding.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
