Abstract A new hydroxyl strontium borate, Sr5[BO2(OH)]3(OH)3F has been synthesized using the hydrothermal method for the first time. It crystallizes in the monoclinic space group P21/m with unit cell parameters a = 5.596(2) A, b = 14.405(5) A, c = 7.591(3) A, β = 101.452(4)°, and Z = 2. The fundamental building block of the structure is a [BO2(OH)]2− unit. Through the investigation with other hydroxyl strontium borates, Sr5[BO2(OH)]3(OH)3F is the first hydroxyborate fluoride with the [BO2(OH)]2− fundamental building block.

Sr5[BO2(OH)]3(OH)3F：具有 [BO2(OH)]2− 单元的第一个羟基硼酸盐氟化物

摘要 首次采用水热法合成了一种新型羟基硼酸锶Sr5[BO2(OH)]3(OH)3F。它在单斜空间群 P21/m 中结晶，晶胞参数 a = 5.596(2) A, b = 14.405(5) A, c = 7.591(3) A, β = 101.452(4)°, and Z = 2 . 该结构的基本组成部分是 [BO2(OH)]2− 单元。通过对其他羟基硼酸锶的研究，Sr5[BO2(OH)]3(OH)3F 是第一个具有 [BO2(OH)]2− 基本结构单元的羟基硼酸盐氟化物。
