Materials Data on Sm2BiO2 by Materials Project
Sm2BiO2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm is bonded in a 4-coordinate geometry to four equivalent Bi and four equivalent O atoms. All Sm–Bi bond lengths are 3.64 Å. All Sm–O bond lengths are 2.30 Å. Bi is bonded in a body-centered cubic geometry to eight equivalent Sm atoms. O is bonded to four equivalent Sm atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra.
