Crystal structure of luliconazole

Abstract

The crystal structure of luliconazole {LCZ; C₁₄H₉Cl₂N₃S₂; systematic name: (E)-[(4R)-4-(2,4-di-chloro-phen-yl)-1,3-di-thio-lan-2-yl-idene](1H-imidazol-1-yl)aceto-nitrile} is reported. In the mol-ecule of the title compound, the di-thiol-ane ring adopts an envelope conformation, while the di-chloro-phenyl ring exhibits disorder. In the crystal packing of luliconazole, only two inter-molecular 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.

Keywords: Hirshfeld surface analysis; crystal structure; luliconazole.
