Single crystals of α-Ba(2)P(2)O(7), dibarium diphosphate, were obtained under hydro-thermal conditions. The structure belongs to the diphosphate A(2)P(2)O(7) series with A being an alkaline earth cation. α-Ba(2)P(2)O(7) crystallizes isotypically with α-Sr(2)P(2)O(7). All atomic sites have site symmetry m with the exception of two O atoms which reside on general positions. Both Ba(2+) cations are coordinated by nine terminal O atoms from eclipsed diphosphate P(2)O(7) anions to form a three-dimensional network throughout the structure.
在水热条件下获得了二钡二磷酸（α-Ba₂P₂O₇）的单晶。该结构属于二磷酸盐A₂P₂O₇系列，其中A为碱土金属阳离子。α-Ba₂P₂O₇与α-Sr₂P₂O₇同型结晶。除了位于一般位置的两个O原子外，所有原子位点的点群对称性均为m。两个Ba²⁺阳离子均由来自重叠二磷酸根P₂O₇阴离子的九个端基O原子配位，从而在整个结构中形成三维网络。
