On the synthesis and crystal structure of praseodymium(III) metaborate molybdate(VI) – PrBO2MoO4

Abstract

Abstract The praseodymium metaborate molybdate(VI) PrBO2MoO4 was synthesized by solid-state reaction methods at 850 °C under an argon atmosphere and identified by its powder X-ray diffraction pattern. The polycrystalline sample was placed in a Walker-type multianvil press, where pressure-induced crystal growth at 1 GPa and 850 °C was successful, yielding single crystals suitable for structure determination. PrBO2MoO4 crystallizes monoclinically in the space group P21/c (no. 14) with the unit cell parameters a = 10.1735(2), b = 4.1479(1), c = 11.9090(3) Å, β = 116.52(1)°, and four formula units per cell.
