The new acentric indium borate InBO(OH) was synthesized in a Walker-type multianvil apparatus at extreme pressure and temperature conditions of 12.3 GPa and 1500 °C. Single-crystal X-ray diffraction provided the data for the crystal structure solution and refinement. InBO(OH) crystallizes in the orthorhombic space group Fdd2 ( Z = 8) with the lattice parameters a = 39.011(8), b = 4.4820(9), c = 7.740(2) Å, and V = 1353.3(5) Å. The structure of InBO(OH) is basically built of corner-sharing BO tetrahedra and isolated InO octahedra. The presence of hydroxyl groups was confirmed with vibrational spectroscopic methods (IR and Raman). Furthermore, the second harmonic signal of an InBO(OH) powder sample yielded more than twice the intensity of quartz.
新型无对称中心的铟硼酸铟 InBO(OH) 是在 Walker 型多砧高压高温设备中，于 12.3GPa 和 1500°C 的极端条件下合成的。单晶 X 射线衍射提供了晶体结构解析和精修的数据。InBO(OH) 属于正交晶系，空间群为 Fdd2（Z=8），晶格参数为 a = 39.011(8)，b = 4.4820(9)，c = 7.740(2)Å，V = 1353.3(5)Å。InBO(OH) 的结构主要由顶角共享的 BO4 四面体和孤立的 InO6 八面体组成。通过振动光谱方法（IR 和 Raman）证实了羟基的存在。此外，InBO(OH) 粉末样品的二次谐波信号强度超过了石英的两倍。
