The compound described by Pr2BiO2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. Pr(1) is bonded in a 4-coordinate geometry to four equivalent Bi(1) and four equivalent O(1) atoms. Bi(1) is bonded in a body-centered cubic geometry to eight equivalent Pr(1) atoms. O(1) is bonded to four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
