Materials Data on Th2P2S by Materials Project
Th2P2S crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one Th2P2S ribbon oriented in the (0, 0, 1) direction. Th4+ is bonded in a linear geometry to one P3- and one S2- atom. The Th–P bond length is 2.74 Å. The Th–S bond length is 2.60 Å. P3- is bonded in a linear geometry to one Th4+ and one P3- atom. The P–P bond length is 1.98 Å. S2- is bonded in a linear geometry to two equivalent Th4+ atoms.
