A second monoclinic polymorph of {2,6-bis[(2,4,5-trifluoro­phen­yl)imino­meth­yl]pyridine-κ³N,N′,N′′}dichloridonickel(II)

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 P2₁/c [Baldovino-Pantaleón 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...π [F...centroid = 2.9676 (14) Å] inter­actions.
