Materials Data on SmPaO4 by Materials Project

PaSmO4 is Fluorite-derived structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Pa5+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Pa–O bond lengths are 2.31 Å. Sm3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sm–O bond lengths are 2.41 Å. O2- is bonded to two equivalent Pa5+ and two equivalent Sm3+ atoms to form a mixture of edge and corner-sharing OSm2Pa2 tetrahedra.
