Materials Data on ThPSe by Materials Project
ThPSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Th4+ is bonded in a 9-coordinate geometry to four equivalent P2- and five equivalent Se2- atoms. All Th–P bond lengths are 2.94 Å. There are four shorter (3.05 Å) and one longer (3.22 Å) Th–Se bond lengths. P2- is bonded in a 4-coordinate geometry to four equivalent Th4+ atoms. Se2- is bonded in a 5-coordinate geometry to five equivalent Th4+ atoms.
