Materials Data on TmPaO4 by Materials Project

PaTmO4 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 2.09 Å. Tm3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Tm–O bond lengths are 2.06 Å. O2- is bonded to two equivalent Pa5+ and two equivalent Tm3+ atoms to form a mixture of edge and corner-sharing OTm2Pa2 tetrahedra.
