An unprecedented nanoscale trilayered polythreading coordination array hierarchically formed from 2D square grid networks and induced by protonated 1,2-bis(4-pyridyl)ethane
Three supramolecular isomeric Cu(ii) networks with different metal fragments and ligand conformations were obtained by the adjustment of solvent molecules.
The aromatic core in dipyridyl linker ligands is found to impact the mode of 2-fold interpenetration in hybrid ultramicroporous materials formed by pillared square grid networks.
