摘要

As shown below (Fig. 1), 1 has two sites for metal–ligand interaction; a simple chelating site analogous to 2,2′-bipyridyl and an exo N-donor site for bridging. Since these two sites are oriented ∼90° to each other, we reasoned that this ligand could be used to assemble simple molecular polygons. There are, of course, two very simple planar polygons that can be generated using four ML units with 90° corners; a square and a rectangle. Which of these is formed ...
