Hi all, I found a likely error in a Materials Project structure and wanted to report it, I hope this is the right place!
The error is in SrAuBi. The Au is in the Wyckoff position 2a and Sr is in 2d, but these are reversed in the listed reference.
(F. Merlo, M. Pani, and M.L. Fornasini. R m x compounds formed by alkaline earths, europium and ytterbium - i. ternary phases with m= cu, ag, au; x= sb, bi. Journal of the Less-Common Metals , 166:319–327, 1990).
Although the paper doesn’t actually list the Wyckoff positions for SrAuBi, it lists them for the isostructural SrAgBi, with Sr in the a2 position. I checked the Materials Project structures for a number of related compounds (SrAgBi, EuAuBi, SrAuSb), and SrAuBi was the only one with this error.
