Crystal structure of luliconazole

Abstract

The crystal structure of luliconazole (LCZ) has been determined. The di­thiol­ane ring adopts an envelope conformation. In the crystal, two inter­molecular C—H⋯N hydrogen bonds are observed.

The crystal structure of luliconazole {LCZ; C₁₄H₉Cl₂N₃S₂; systematic name: (E)-[(4R)-4-(2,4-di­chloro­phen­yl)-1,3-di­thio­lan-2-yl­idene](1H-imidazol-1-yl)aceto­nitrile} is reported. In the mol­ecule of the title compound, the di­thiol­ane ring adopts an envelope conformation, while the di­chloro­phenyl ring exhibits disorder. In the crystal packing of luliconazole, only two inter­molecular C–H⋯N hydrogen bonds are observed. Hirshfeld surface analysis reveals that the most dominant contacts are H⋯N/N⋯H, H⋯Cl/Cl⋯H, H⋯H and C⋯H/H⋯C.
