Pr₃Mo₄B₆O₂₄(OH)₃: High‐Pressure/High‐Temperature Synthesis of an Acentric Rare Earth Molybdenum Borate

Abstract

We report on the synthesis of a new praseodymium molybdenum borate under high‐pressure/high‐temperature conditions. The new compound with the sum formula Pr3Mo4B6O24(OH)3 crystallizes acentrically in the monoclinic space group Cm displaying a new structure type. The structure was solved via single‐crystal structure determination. Additionally, the proposed structural model was confirmed by powder X‐ray diffraction, second harmonic generation measurement, and single‐crystal infrared and Raman spectroscopic investigation.
