Supramolecular structures are generated from manganese thiodiacetate (tda) units and substituted bipyridine (bipy) ligands (see pictures). Analysis of the π-stacking and DFT calculations for isolated binuclear units suggest that, in some cases, the geometry of the building blocks depends ultimately on the strength of noncovalent interactions between the 1D coordination polymers.
