Novel Synthetic Approach to Trinuclear 3d‐4f Complexes: Specific Exchange of the Central Metal of a Trinuclear Zinc(<scp>II</scp>) Complex of a Tetraoxime Ligand with a Lanthanide(<scp>III</scp>) Ion

Abstract

Only the central metal atom of the homotrinuclear complex [LZn3]2+, prepared by cooperative complexation between a linear ligand and Zn(OAc)2, is replaced with a Ln3+ ion by selective and quantitative transmetalation to give a helical heterotrinuclear complex [LZn2Ln]3+ (see scheme). Ln=lanthanide. Supporting information for this article is available on the WWW under http://www.wiley-vch.de/contents/jc_2002/2002/z19528_s.pdf or from the author.
