The self‐assembly of the terdentate ligands 1a–h, based on terpyridine‐like binding sites, with octahedrally coordinated metal ions, such as Fe II , Co II , Cu II , Zn II , Cd II , Hg II and Pb II , leads to the formation of the supramolecular grid‐type complexes 2a–c(M II ), 3d–g(M II ) and 4h(M II ). The structures and compositions of these coordination complexes in solution were deduced from electrospray mass spectrometry (ESMS) measurements. The results agree with the data available from x‐ray radiocrystallography in the solid state and/or NMR spectroscopy in solution. ESMS may be applied in cases where other methods are difficult to use or inconclusive. This study stresses the power of ESMS in supramolecular chemistry. Copyright © 2001 John Wiley & Sons, Ltd.
