Th2PSe2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Th2PSe2 cluster. Th(1) is bonded in a linear geometry to one P(1) and one Se(1) atom. P(1) is bonded in a linear geometry to two equivalent Th(1) atoms. Se(1) is bonded in a single-bond geometry to one Th(1) atom.
