Two new orthophosphates, BaMnFe(PO) [barium dimanganese(II) iron(III) tris-(orthophosphate)] and SrMnFe(PO) [strontium dimanganese(II) iron(III) tris-(orthophosphate)], were synthesized by solid-state reactions. They are isotypic and crystallize in the ortho-rhom-bic system with space group type . Their crystal structures comprise infinite zigzag chains of edge-sharing FeO octa-hedra (point group symmetry .2.) and MnO double octa-hedra running parallel to [001], linked by two types of PO tetra-hedra. The so-formed three-dimensional framework delineates channels running along [001], in which the alkaline earth cations (site symmetry .2.) are located within a neighbourhood of eight O atoms.
通过固态反应合成了两种新型正磷酸盐，即BaMnFe(PO) [钡二锰(II)铁(III)三(正磷酸盐)]和SrMnFe(PO) [锶二锰(II)铁(III)三(正磷酸盐)]。它们是同型的，结晶于正交晶系，空间群类型为 。它们的晶体结构由沿[001]方向平行排列的无限之字形链组成，这些链由边共享的FeO八面体（点群对称性.2.）和MnO双八面体构成，通过两种类型的PO四面体相连。如此形成的三维骨架勾勒出沿[001]方向的通道，碱土金属阳离子（位点对称性.2.）位于八个O原子的邻域内。
