Materials Data on Pr3Se4 by Materials Project
Pr3Se4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Pr is bonded to eight equivalent Se atoms to form a mixture of distorted corner, edge, and face-sharing PrSe8 hexagonal bipyramids. There are four shorter (3.04 Å) and four longer (3.20 Å) Pr–Se bond lengths. Se is bonded to six equivalent Pr atoms to form a mixture of distorted corner, edge, and face-sharing SePr6 octahedra. The corner-sharing octahedra tilt angles range from 17–50°.
