Published on: July 28, 2022
(5Z)-5-(2-Hydroxy-benzyl-idene)-2-thioxo-1,3-thia-zolidin-4-one methanol hemisolvate
Abstract:
In the title compound, C(10)H(7)NO(2)S(2)·0.5CH(3)OH, the dihedral angle between the aromatic rings is 11.43 (11)° and a short intra-molecular C-H⋯S contact occurs. The methanol solvent mol-ecule is equally disordered over two sets of sites. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. The methanol solvent mol-ecule connects the dimers through O-H⋯S and O-H⋯O inter-molecular hydrogen bonds. Further stability is afforded by C-H⋯π and π-π inter-actions [centroid-centroid separation = 3.5948 (13) Å].

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.
