Abstract

A new three-dimensional (3-D) open-framework manganese borophosphate, (NH4)6[Mn3B6P9O 36(OH)3]·4H2O (denoted as MnBPO-CJ31), has been synthesized by using boric acid flux method. Its anionic framework structure is constructed by the connection of MnO6 octahedra and BO4, PO4 and PO3(OH) tetrahedra. It contains 12-ring channels along the [001] direction with a pore diameter of 7.1 Å. It is the first borophosphate featuring a 3-D anionic partial structure with a B/P ratio of 2/3 and an unprecedented fifteen mer tetrahedral fundamental building unit (FBU) [B6P9O36(OH)3] exists in this compound. NH4+ ions locate in the void space to balance the negative charge of the inorganic framework. The compound is further characterized by powder XRD, ICP, CHN, TGA and IR analyses. Magnetic study reveals that MnBPO-CJ31 shows interesting canted antiferromagnetic behaviour at low temperature.
