Abstract

The trigonal indium borate In₁₉B₃₄O₇₄(OH)₁₁ was synthesized in a Walker-type multianvil apparatus under high-pressure/high-temperature conditions of 13 GPa and 1150 °C. The crystal structure could be determined by single-crystal X-ray diffraction data collected at room temperature. In₁₉B₃₄O₇₄(OH)₁₁ crystallizes in the trigonal space group R3̅ (Z = 3) with the lattice parameters a = 1802.49(6) pm, c = 1340.46(5) pm, and V = 3.7716(3) nm³. The structure of In₁₉B₃₄O₇₄(OH)₁₁ contains alternating B-O T2 supertetrahedra units. The presence of hydroxyl groups was confirmed with vibrational spectroscopic methods such as Raman and IR. Besides H₂InB₅O₁₀, In₁₉B₃₄O₇₄(OH)₁₁ is now the second known compound in the system In-B-O-H.
