| Abstract: | The indium oxide‐borate In4O2B2O7 was synthesized under high‐pressure/high‐temperature conditions at 12.5 GPa/1420 K using a Walker‐type multianvil apparatus. Single‐crystal X‐ray structure elucidation showed edge‐sharing OIn4 tetrahedra and B2O7 units building up the oxide‐borate. It crystallizes with Z = 8 in the monoclinic space group P21/n (no. 14) with a = 1016.54(3), b = 964.55(3), c = 1382.66(4) pm, and β = 109.7(1)°. The compound was also characterized by powder X‐ray diffraction and vibrational spectroscopy. |
