A high-pressure/high-temperature experiment at 7.5 GPa and 1673 K led to the formation of the new compound βY2B4O9. In contrast to the already known polymorph αY2B4O9, which crystallizes in the space group C2/c, the reported structure could be solved via single-crystal Xray diffraction in the triclinic space group P1 (no. 2) and is isotypic to the already known lanthanide borates βDy2B4O9 and βGd2B4O9. Furthermore, the photoluminescence of an europium doped sample of βY2B4O9:Eu3+ (8%) was investigated.

AbstractOrthorhombic dysprosium orthogallate DyGaO3 and trigonal gallium orthoborate GaBO3 were synthesized in a Walker-type multianvil apparatus under high-pressure/high-temperature conditions of 8.5 GPa/1350 °C and 8 GPa/700 °C, respectively. Both crystal structures could be determined by single-crystal X-ray diffraction data collected at room temperature. The orthorhombic dysprosium orthogallate crystallizes in the space group Pnma (Z = 4) with the parameters a = 552.6(2), b = 754.5(2), c = 527.7(2) pm, V = 0.22002(8) nm3, R1 = 0.0309, and wR2 = 0.0662 (all data) and the trigonal compound GaBO3 in the space group R3̅c (Z = 6) with the parameters a = 457.10(6), c = 1419.2(3) pm, V = 0.25681(7) nm3, R1 = 0.0147, and wR2 = 0.0356 (all data).

The rare-earth borate Sc3B5O12 was synthesized under high-pressure / high-temperature conditions of 6 GPa and 1100 °C in a Walker-type multianvil apparatus. The single-crystal structure determination revealed an isotypy to RE3B5O12 (RE = Er-Lu). Sc3B5O12 crystallizes in the rare space group Pmna (Z = 4) with the parameters a = 1245.4(3), b = 443.46(9), c = 1222.1(2) pm, V = 0.675(1) nm3, R1 = 0.0520, and wR2 = 0.0860 (all data). The structure of Sc3B5O12 is composed of layers of condensed BO4 tetrahedra, separated by eight-fold coordinated scandium ions
