Abstract

A series of potassium rare earth double vanadates is presented. Single crystals of double vanadates with stoichiometry K₃Ln(VO₄)₂ (Ln = La, Pr, Nd, and Sm) and crystallizing in the glaserite structure type were synthesized via a molten alkali chloride/fluoride flux reaction. Different structures were observed depending on the constituent rare earth: K₃La(VO₄)₂ crystallizes in an as-of-yet unreported modification of the typical glaserite structure in the space group P2₁/c, likely due to its larger ionic size that results in an increase in the lanthanide coordination number (seven to eight). The Pr, Nd, and Sm compositions are isostructural with their phosphate analogues and crystallize in the space group P2₁/m. A discussion of the synthetic details, structure determination, structure descriptions, and coordination number variance is presented.
