The asymmetric unit of the title compound, [NiCl2(C19H9F6N3)], contains one half-molecule residing on a crystallographic twofold rotation axis. The title compound crystallizes in space group C2/c while the previously reported polymorph was reported in P2(1)/c [Baldovino-Pantaleon et al. (2006). Adv. Synth. Catal. 348, 236-242]. The Ni2+ ion exhibits a pentacoordinate distorted trigonal-bipyramidal NiCl2N3 geometry, with two Cl atoms in the equatorial plane. In the crystal, molecules are linked by intermolecular C-F center dot center dot center dot pi [F center dot center dot center dot centroid = 2.9676 (14) angstrom] interactions.
