Materials Data on CePaO4 by Materials Project
PaCeO4 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 2.33 Å. Ce3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ce–O bond lengths are 2.42 Å. O2- is bonded to two equivalent Pa5+ and two equivalent Ce3+ atoms to form a mixture of edge and corner-sharing OCe2Pa2 tetrahedra.
