Self-Assembly of Discrete Organometallic−Organic Hybrid Supramolecular Arrays from Ferrocenyl Dipyridines and Terephthalic and Trimesic Acids

Reactions of ferrocenyl dipyridines (1a,b) with terephthalic (2) and trimesic acid (4) form [2+2] and [3+2]
supramolecular assemblies 3 and 5, respectively. Crystallographic analyses reveal that they are stabilized by cooperative
noncovalent interactions involving multiple hydrogen-bonding and π−π interactions.
