Abstract

The search for compounds with the formula composition KBaR(BO₃)₂ has been performed by solid-phase synthesis and differential thermal analysis. The compounds synthesized in this series are KBaPr(BO₃)₂ and KBaNd(BO₃)₂, which are isostructural to KBaY(BO₃)₂, are isotypical to butschliite K₂Ca(CO₃)₂, and crystallize in a trigonal system with space group R3m. The structural characteristics of compounds calculated for the entire series of REEs are given.
