Metal-Directed Self-Assembly of a Zn~(II)-salpyr Complex into a Supramolecular Vase Structure

摘要

A new type of supramolecular building block,Zn~(II)-salpyr [salpyr = N,N'-3-pyridylenebis(salicylideneimine)],is described that contains both a pyridyl donor and a Lewis acidic Zn~(II)acceptor site in the salen framework.As a consequence,this building block self-organizes into a stable tetrameric vase structure via cooperative intermolecular Zn-N_(pyr)interactions.
