Vacancy-ordered 12H-type hexagonal perovskites Ba 6 Ru 2 Na 2 X 2 O 17 (X = P, V) with a ( c ’ cchcc ) 2 stacking sequence of [BaO 3 ] c , [BaO 3 ] h , and [BaO 2 ] c ’ layers, where c and h represent a cubic and hexagonal stacking sequence, were previously reported by Quarez et al. in 2003. They also synthesized Ba 6 Ta 2 Na 2 V 2 O 17 , but structural refinement was absent. Very recently, Szymanski et al. reported 43 new compounds, including 12H-type Ba 6 Ta 2 Na 2 V 2 O 17 , using large-scale ab initio phase-stability data from the Materials Project and Google DeepMind with the assistance of an autonomous laboratory. But their structural refinement was very poor. Here, we report the synthesis and structure of Ba 6 Ta 2 Na 2 V 2 O 17 , which does not have 12H-type structure but has a vacancy-ordered 6C-type perovskite with a ( c ’ ccccc ) stacking sequence of [BaO 3 ] c and [BaO 2 ] c ’ layers. We also report the phosphite analogue Ba 6 Ta 2 Na 2 P 2 O 17 as a new compound. We claim an importance of careful structural characterization on newly discovered compounds; otherwise, the database constructed will lose credibility. |
