Abstract: In the title compound, [Ni(C₁₄H₁₂N₄)₂](ClO₄)₂·2CHCl₃, each of the two crystallographically independent nickel(II) complex molecules lies on a twofold axis. In each case, the Ni^II atom is coordinated by the six N atoms of two 2-[3-(2-pyridyl)pyrazol-1-ylmethyl]pyridine ligands in a distorted octahedral geometry. The Ni-N_pyrazole bond lengths [1.977 (3)-1.997 (4) Å] are appreciably shorter than the Ni-N_pyridine bond lengths [2.133 (4)-2.184 (4) Å].
