Ambidentate Pyridyl-carboxylate Ligands in the Coordination-Driven Self-Assembly of 2D Pt Macrocycles: Self-Selection for a Single Isomer

The coordination-driven self-assembly of discrete 2D macrocyclic species from ambidentate
pyridyl-carboxylate-based donor ligands and platinum-containing acceptors is presented. All these species
are characterized by electrospray ionization mass spectrometry (ESIMS), multinuclear NMR, and in one
example, X-ray crystallography. In each case only one isomeric assembly is selectively formed in high
yield, despite the potential for more than one product as a consequence of differences in connectivity.
