A double helix is the repeating unit in a luminescent calcium 5-aminoisophthalate supramolecular edifice with water-filled hexagonal channels.
Calcium 5-aminoisophthalate {[Ca(AIP)(OH2)4](H2O)} proportional, variant (1), synthesized from Ca(OH)2 and H2AIP, exists as a double helix. Hydrogen-bonding interactions between metal-bound water molecules, carboxylate oxygen, and the -NH2 group result in the formation of a supramolecular assembly, where the double helices are connected to each other to form hexagonal channels filled with water molecules.
