Materials Data on PrHSe by Materials Project
PrHSe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr3+ is bonded in a distorted trigonal planar geometry to three equivalent H1- and six equivalent Se2- atoms. All Pr–H bond lengths are 2.35 Å. All Pr–Se bond lengths are 3.09 Å. H1- is bonded in a trigonal planar geometry to three equivalent Pr3+ atoms. Se2- is bonded to six equivalent Pr3+ atoms to form a mixture of edge, face, and corner-sharing SePr6 octahedra. The corner-sharing octahedral tilt angles are 45°.
