N2 - A new three-dimensional (3-D) open-framework vanadium (IV) borophosphate, Na2[VB3P2O12(OH)] · 2.92H2O (denoted as VBPO-CJ27), has been synthesized by using boric acid flux method. Single-crystal structure analysis reveals that its structure is constructed by the connection of VOD octahedra, PO4 and BO 4 tetrahedra, and BO2(OH) trigonal planes to form a 3-D anionic framework containing intersecting 8-, 12-, and 16-ring channels. Charge neutrality is achieved by Na+ ions, and the guest water molecules locate in the void space of the open framework. To the best of our knowledge, it is the first borophosphate with extra-large 16-ring openings. Interestingly, its structure features unprecedented 128166 super cavities. The compound is further characterized by SEM, powder XRD, ICP, TGA, and IR analyses. Its magnetic property and ion-exchange capacity are also studied. The magnetic measurement reveals that VBPOCJ27 is paramagnetic. Ion-exchange studies show that Na+ ions can be partially exchanged by NH4 + ions.
