Metal-ligand interactions, supramolecular

Sanders (83) constructed a supramolecular assembly of heterometal-lic porphyrins held together by different types of metal-ligand interaction. The team exploited the different kinetic and thermodynamic properties of the pyridine-zinc, carboxylate-tin, and pyridine-... 

As stated above, several supramolecular motifs such as hydrogen-bonding, donor-acceptor, or metal-ligand interactions have been used to promote the organization of Pcs in solution. Somehow different, and probably to some extent more complex, is the case when such organization is sought on solid supports, as in this latter case the interactions between the macrocycles and the surface itself should also be taken into account. 

Our aim in this work is to present a qualitative description of the properties of the most relevant intermolecular interactions from the point of view of the packing of molecular crystals. Therefore, we will not deal with the properties of metal-ligand interactions, at the root of much of supramolecular chemistry, as they do not play a leading role in the crystal packing of organometallic compounds. For the... 

The more versatile and stable modular interface was successfully used to investigate supramolecular complexations based on the metal-ligand interaction between Zn-porphyrin 1 and the nitrogen-containing guest molecules 2, 3, 4, 5 and 6 or the encapsulation of guests 8 and 9 in the cavity of p-CD (7).
