Materials Data on PrBi2IO4 by Materials Project
PrBi2O4I is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Pr3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Pr–O bond lengths are 2.50 Å. Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent I1- atoms. All Bi–O bond lengths are 2.28 Å. All Bi–I bond lengths are 3.69 Å. O2- is bonded to two equivalent Pr3+ and two equivalent Bi3+ atoms to form a mixture of corner and edge-sharing OPr2Bi2 tetrahedra. I1- is bonded in a distorted body-centered cubic geometry to eight equivalent Bi3+ atoms.
