Synthesis and Some Properties of Lanthanide Bromotungstates

Lanthanide bromotungstates LnWO4Br, where Ln = Pr, Nd, Gd, or Y, are obtained for the first time by solid-state synthesis starting from lanthanide oxobromides and tungsten trioxide. The compounds were identified based on chemical, crystal-optical, and X-ray powder diffraction evidence. The thermal stability was determined, and the unit cell parameters were calculated for the compounds under study.
