Materials Data on Pr3In by Materials Project
Pr3In is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr is bonded to eight equivalent Pr and four equivalent In atoms to form distorted PrPr8In4 cuboctahedra that share corners with twelve equivalent PrPr8In4 cuboctahedra, edges with eight equivalent InPr12 cuboctahedra, edges with sixteen equivalent PrPr8In4 cuboctahedra, faces with four equivalent InPr12 cuboctahedra, and faces with fourteen equivalent PrPr8In4 cuboctahedra. All Pr–Pr bond lengths are 3.56 Å. All Pr–In bond lengths are 3.56 Å. In is bonded to twelve equivalent Pr atoms to form InPr12 cuboctahedra that share corners with twelve equivalent InPr12 cuboctahedra, edges with twenty-four equivalent PrPr8In4 cuboctahedra, faces with six equivalent InPr12 cuboctahedra, and faces with twelve equivalent PrPr8In4 cuboctahedra.
