Abstract: The title compound, [NiCl₂(C₃₀H₂₆N₄)], is a monoclinic (purple) racemic polymorph of a previously reported orthorhombic (blue) form of the same compound. The complex exhibits pseudo-tetrahedral coordination geometry around the nickel(II) metal center. This geometry is enforced by the geometrically constraining ligand 2,2'-bis(1-ethylbenzimidazol-2-yl)biphenyl.
