In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Ba–I bond distances ranging from 3.50–3.80 Å. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Ba–I bond distances ranging from 3.49–3.91 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Ba–I bond distances ranging from 3.50–4.16 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in an octahedral geometry to six I1- atoms. There are a spread of Y–I bond distances ranging from 3.02–3.07 Å. In the second Y3+ site, Y3+ is bonded in an octahedral geometry to six I1- atoms. There are a spread of Y–I bond distances ranging from 3.01–3.09 Å. There are fourteen inequivalent I1- sites.
