Materials Data on ThPS by Materials Project
ThPS 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 S2- atoms. All Th–P bond lengths are 2.96 Å. There are four shorter (2.92 Å) and one longer (3.00 Å) Th–S bond lengths. P2- is bonded in a 8-coordinate geometry to four equivalent Th4+ atoms. S2- is bonded to five equivalent Th4+ atoms to form a mixture of distorted edge and corner-sharing STh5 trigonal bipyramids.
