The chiral synthons (S-)-1-phenyl-N-(pyridine-2-yl)ethylidine)ethanamine (L1), (R-)-1phenyl-N-(pyridine-2-yl)ethylidine))ethanamine (L2) (S)-1-phenyl-N-(pyridine-2-yl methylene) ethanamine (L3), and (R)-1-phenyl-N-(pyridine-2-yl methylene) ethanamine (L4) were synthesized in good yields. Treatments of L1-L4 with NiBr(DME) and NiCl precursor afforded dinuclear complexes [Ni(L1)-μ-Br]NiBr (Ni1), [Ni(L2)-μ-Br]NiBr (Ni2), [Ni(L3)-μBr]Br (Ni3), [Ni(L4)-μ-Br]NiBr (Ni4) and [Ni(L4)Cl] (Ni5). The identities of the compounds were established using NMR, FT-IR and EPR spectroscopy, mass spectrometry, magnetic moments, elemental analysis and single crystal X-ray crystallography.
