trans-(1,8-Dibenzyl-1,3,6,8,10,13-hexa­azacyclo­tetra­deca­ne)diisonicotinatonickel(II)

In the centrosymmetric title compound, [Ni(C(6)H(4)NO(2))(2)(C(22)H(34)N(6))], the Ni(II) ion is bonded to the four secondary N atoms of the macrocyclic ligand in a square-planar fashion and two carboxyl­ate O atoms of the isonicotinate ions in axial positions, resulting in a tetra­gonally distorted octa­hedron. An offset face-to-face π–π stacking inter­action [centroid–centroid distance = 3.674(4) Å] and N—H⋯N and N—H⋯O hydrogen-bonding inter­actions give rise to a one-dimensional supra­molecular structure in the solid state.
