Hydrogen-bonding inter­actions involving the perchlorate anions in the crystal packing [NiL](ClO4)2. Light-green dashed lines indicate N—H⋯O and C—H⋯O hydrogen-bonding inter­actions. Symmetry codes: (i) 1 − x, y, [{1\over 2}] − z; (ii) 1 − x, 1 − y, 1 − z; (iii) x, −[{1\over 2}] + y, 1 − z; (v) [{3\over 2}] − x, [{1\over 2}] − y, 1 − z; (vi) −[{1\over 2}] + x, [{1\over 2}] − y, −[{1\over 2}] + z. Only one of the whole-mol­ecule disorder [NiL]2+ components and the major component of the perchlorate anion are shown.
