PrHSe crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a distorted trigonal planar geometry to three equivalent H(1) and six equivalent Se(1) atoms. H(1) is bonded in a trigonal planar geometry to three equivalent Pr(1) atoms. Se(1) is bonded to six equivalent Pr(1) atoms to form a mixture of face, corner, and edge-sharing SePr6 octahedra. The corner-sharing octahedral tilt angles are 45°.
