1,2-Bis(phenylthio)ethane is a molecular compound that has two geometric isomers (E and Z). It is a colorless liquid with a sweet odor and can be obtained by reacting dimethylformamide with ruthenium chloride. The E-isomer has been characterized by x-ray crystallography, whereas the Z-isomer was characterized using NMR spectroscopy. The E-isomer has three phenyl groups that are hydrogen bonded to each other, while in the Z-isomer there are two phenyl groups that are hydrogen bonded to each other. 1,2-Bis(phenylthio)ethane is stable in organic solvents such as chloroform and benzene and reacts with butyllithium to form the corresponding lithium derivative. The compound shows fluorescence properties when it is irradiated with UV light.
