A new open-framework structure of nickel complex pillared aluminophosphate [C6N4H20]2[Ni(Al3P4O16)2]

Al3P4O163- layers with 4.6-net are linked each other by using NiO2N4 octahedra as the pillars, forming a new open-framework nickel aluminophosphate [C6N4H20]2[Ni(Al3P4O16)2] (designed NiAPO-CJ18) with intersecting 16-MR and 12-MR channels.
