Crystal structures and comparisons of huntite aluminum borates REAl₃(BO₃)₄ (RE = Tb, Dy and Ho).

ABSTRACT: Three huntite-type aluminoborates of stoichiometry REAl₃(BO₃)₄ (RE = Tb, Dy and Ho), namely, terbium/dysprosium/holmium trialuminium tetrakis(borate), were synthesized by slow cooling within a K₂Mo₃O₁₀ flux with spontaneous crystallization. The crystal structures were determined using single-crystal X-ray diffraction (SC-XRD) data. The synthesized borates are isostructural to the huntite [CaMg₃(CO₃)₄] structure and crystallized within the trigonal R32 space group. The structural parameters were compared to literature data of other huntite REAl₃(BO₃)₄ crystals within the R32 space group. All three borates fit well into the tre
