A new three-dimensional (3-D) open-framework manganese borophosphate, (NH(4))(6)[Mn(3)B(6)P(9)O(36)(OH)(3)]·4H(2)O (denoted as MnBPO-CJ31), has been synthesized by using boric acid flux method. Its anionic framework structure is constructed by the connection of MnO(6) octahedra and BO(4), PO(4) and PO(3)(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) [B(6)P(9)O(36)(OH)(3)] exists in this compound. NH(4)(+) 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.
一种新的三维（3-D）开架式锰硼磷酸盐，(NH(4))(6)[Mn(3)B(6)P(9)O(36)(OH)(3)]·4H(2)O（表示为 MnBPO-CJ31），是通过使用硼酸助熔剂方法合成的。其阴离子骨架结构由 MnO(6)八面体和 BO(4)、PO(4)和 PO(3)(OH)四面体连接而成。它沿着[001]方向包含 12 元环通道，孔径为 7.1 Å。这是第一个具有 3-D 阴离子部分结构的硼磷酸盐，B/P 比为 2/3，并且在该化合物中存在前所未有的十五元四面体基本结构单元（FBU）[B(6)P(9)O(36)(OH)(3)]。NH(4)(+)离子位于空隙中以平衡无机骨架的负电荷。该化合物还通过粉末 XRD、ICP、CHN、TGA 和 IR 分析进行了进一步的表征。磁性研究表明，MnBPO-CJ31 在低温下表现出有趣的倾斜反铁磁行为。
