所有原子都处于一般位置。基于 844 次反射的最小二乘细化得出 R = 0.06。硼的位置坐标精度为 0.006/~，氧为 0"003/~，氢为 0.07 A。该结构由组成 [BaO4(OH)(OH2)]o o 的无限之字形链组成，沿着 b 轴定向，链之间有氢键。三分之二的硼原子呈三角形，三分之一为四面体构型。水氧是 BO 的不共享角在 4 个四面体中，羟基氧位于三角形 BO 的未共享角上，而其他每个氧原子均与两个硼原子键合。
All atoms are in general positions. Least-square refinements based on 844 reflections gave R = 0.06. The position coordinates have been determined to a precision of 0.006/~ for boron, 0"003/~ for oxygen and 0.07 A for hydrogen. The structure consists of endless zigzag chains of composition [BaO4(OH)(OH2)]o o directed along the b-axis with hydrogen bonds between the chains. Two thirds of the boron atoms are in triangular and one third in tetrahedral configuration. The water oxygen is an unshared corner of a BO 4 tetrahedron, the hydroxyl oxygen an unshared corner of a BO a triangle, while each of the other oxygen atoms is bonded to two boron atoms.
