Materials Data on Y(BiO2)3 by Materials Project
Y(BiO2)3 is Ilmenite-like structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.29 Å. In the second Y3+ site, Y3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.29 Å. Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.23–2.63 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Y3+ and three equivalent Bi3+ atoms to form a mixture of distorted edge and corner-sharing OYBi3 trigonal pyramids. In the second O2- site, O2- is bonded to one Y3+ and three equivalent Bi3+ atoms to form a mixture of distorted edge and corner-sharing OYBi3 trigonal pyramids.
