Na3PSe4 crystallizes in the cubic I-43m space group. The structure consists of a Na3PSe4 framework. Na(1) is bonded in a 4-coordinate geometry to four equivalent Se(1) atoms. P(1) is bonded in a tetrahedral geometry to four equivalent Se(1) atoms. Se(1) is bonded to three equivalent Na(1) and one P(1) atom to form a mixture of edge and corner-sharing SeNa3P trigonal pyramids.
