The title compound, (systematic name:N,N′-dibenzyl-3,3′-dimethoxy-1,1′-biphenyl-4,4′-diamine), C28H28N2O2, was synthesized by the reduction of a Schiff base preparedviaa condensation reaction betweeno-dianisidine and benzaldehyde under acidic conditions. The molecule lies on a crystallographic inversion centre so that the asymmetric unit contains one half-molecule. The biphenyl moiety compound is essentially planar. Two intramolecular N—H...O hydrogen bonds occur. The dihedral angle between the terminal phenyl and phenylene rings of a benzidine unit is 48.68 (6)°. The methylene C atom of the benzyl group is disordered over two sets of sites, with occupancy ratio 0.779 (18):0.221 (18). In the crystal, molecules are connected by hydrogen bonding betweeno-dianisidine O atoms and H atoms of the terminal benzyl groups, forming a one-dimensional ladder-like structure. In the data from DFT calculations, the central biphenyl showed a twisted conformation.

The title compound, [Ni(C6H4NO2)2(C16H38N6)], was prepared through self-assembly of a nickel(II) azamacrocyclic complex with isonicotinic acid. The NiIIatom is located on an inversion center and exhibits a distorted octahedral N4O2coordination environment, with the four secondary N atoms of the azamacrocyclic ligand in the equatorial plane [average Ni—Neq= 2.064 (11) Å] and two O atoms of monodentate isonicotinate anions in axial positions [Ni—Oax= 2.137 (1) Å]. Intramolecular N—H...O hydrogen bonds between one of the secondary amine N atoms of the azamacrocyclic ligand and the non-coordinating carboxylate O atom of the anion stabilize the molecular structure. Intermolecular N—H...N hydrogen bonds, as well as π–π interactions between neighbouring pyridine rings, give rise to the formations of supramolecular ribbons extending parallel to [001].
