Crystal structure of 4-bromo-3-[(5-bromo-thio-phen-2-yl)methyl-idene]-2-(di-cyano-methyl-idene)-5,6-di-fluoro-2,3-di-hydro-inden-1-one.

In the mol-ecular structure of the title compound, C17H4Br2F2N2OS, the indenone moiety is close to planar [the dihedral angle between the phenyl and the five-membered ring plane is 4.2 (4)°], and the thio-phene ring is only slightly inclined to this fragment. In the extended structure, a short Br⋯O contact considered as a halogen bond and a weak C-H⋯N inter-action contribute to the crystal packing.
