Materials Data on Pr2BiO2 by Materials Project
Pr2BiO2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr is bonded in a 4-coordinate geometry to four equivalent Bi and four equivalent O atoms. All Pr–Bi bond lengths are 3.71 Å. All Pr–O bond lengths are 2.36 Å. Bi is bonded in a body-centered cubic geometry to eight equivalent Pr atoms. O is bonded to four equivalent Pr atoms to form a mixture of edge and corner-sharing OPr4 tetrahedra.
