Materials Data on Th(PS3)2 by Materials Project

Abstract

Th(PS3)2 crystallizes in the tetragonal P4_2/m space group. The structure is one-dimensional and consists of one Th(PS3)2 ribbon oriented in the (0, 0, 1) direction. Th4+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (2.84 Å) and four longer (3.04 Å) Th–S bond lengths. P4+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are two shorter (2.02 Å) and one longer (2.06 Å) P–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to two equivalent Th4+ and one P4+ atom. In the second S2- site, S2- is bonded in an L-shaped geometry to one Th4+ and one P4+ atom.
