Robert LaDuca, and colleagues at Michigan State University, have hydrothermally synthesised divalent metal coordination polymers featuring the ligand, 3-pyridylisonicotinamide (3-pina). The 3-pina ligand has a hydrogen bonding donor and acceptor locus at its central amide, making supramolecular structure direction achievable, something that is not possible using the regularly tested ligand, 4,4′-bipyridine.
The 3-pyridylisonicotinamide ligand has a kinked disposition of its nitrogen atoms.
The team discuss 3 very diverse structures featuring the 3-pina ligand, showing that the dimensionality in the resulting coordination polymers very much depends on the metal coordination environment and the sulfate binding mode that occurs in each case.
