Overview

A new potentially octadentate N2O^sub 6^ Schiff base ligand, H2L derived from the condensation of 2,2'-(1,1'-binaphthyl-2,2'-diylbis(oxy))dianiline and o-vanillin, along with its copper(II) and zinc(II) complexes, is synthesized and has been characterized by elemental analyses, IR, UV-vis, ^sup 1^H and ^sup 13^C NMR spectra, as well as conductivity measurements. H2L forms mononuclear complexes of 1:1 (metal:ligand) stoichiometry with Cu(II) and Zn(II), and conductivity data confirm the non-electrolyte nature of these complexes. The [ZnL] and [CuL] complexes display very different solid-state structures, as determined by X-ray crystallography. While the [ZnL] complex has a distorted octahedral geometry about the metal, the [CuL] complex displays a distorted square planar geometry about the copper, with long Cu-O(ether) distances of 2.667 .[PUBLICATION ABSTRACT]
