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

Abstract

In the centrosymmetric title compound, [Ni(C6H4NO2)2(C22H34N6)], the NiII 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.
