Materials Data on Pr3S4 by Materials Project
Pr3S4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Pr is bonded to eight equivalent S atoms to form a mixture of distorted face, edge, and corner-sharing PrS8 hexagonal bipyramids. There are four shorter (2.92 Å) and four longer (3.07 Å) Pr–S bond lengths. S is bonded to six equivalent Pr atoms to form a mixture of distorted face, edge, and corner-sharing SPr6 octahedra. The corner-sharing octahedra tilt angles range from 17–50°.
