Abstract
The supramolecular compounds, [Ni(C20H32N8)(en)](ClO4)2 · 2 H2O (1), [Ni(C20H32N8)(isonicotinate)2] (2), and [Ni(C20H32N8)(BQDC)] · 3 H2O (3), have been constructed by the self-assembly of a nickel(II) macrocyclic complex containing pyridyl pendant rings, [Ni(C20H32N8)](ClO4)2 · 2 H2O, with ethylenediamine (hereafter noted en), isonicotinic acid, and potassium 2,29-biquinoline-4,49-dicarboxylate, (K2BQDC · 3 H2O), respectively, in MeCN/H2O. The X-ray crystal structure of 1 indicates that one en coordinates a nickel(II) macrocyclic complex to form a folded macrocyclic complex, which ends up with a stacking dimer via C−H···π and offset face-to-face π−π interactions between the pyridine pendant groups. The X-ray crystal structure of 2 indicates that two isonicotinate ions coordinate a nickel(II) macrocyclic complex at the axial positions and the pyridine groups of the
