Metal-directed self-assembly of a Zn(II)-salpyr complex into a supramolecular vase structure.
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.
