摘要：

The symmetric 'end-off' compartmental proligand 2,6-[N,N'-bis(2-hydroxy-phenylmethyl)-N,N'-bis(2-pyridylmethyl)aminomethyl]-4-methylphenol (H3L) has been used to generate homodinuclear nickel(II) and zinc(II) complexes. The crystal structures of the complexes reveal that the di-nickel(II) complex is donor asymmetric and the di-zinc(II) complex is coordination number asymmetric. In both complexes non-coordinated acetic acid molecules are tightly hydrogen-bonded to the pendant phenols of the ligand generating a double acid salt of the type [CH3COO . . .H . . .L . . .H . . . OOCCH3](3-) in the dinickel complex and a single acid salt of the type [CH3COO . . .H . . .L](3-) in the dizinc complex. In both cases the ligand periphery has been extended to provide a supraligand in which the donor potential of the original ligand has been enhanced.
