A new open-framework magnesium aluminophosphate MgAlP2O7(OH)(H2O)2 (denoted as JU102) has been hydrothermally synthesized by using an organotemplate-free synthetic route in the Al2O3-P2O5-MgO-H2O system. JU102 exhibits novel 4-connected zeolite-like topology with 8-ring channels. The existence of coordinated water and extensive H-bonds in the structure endows JU102 with unique proton conduction...
