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.

Materials Data on Pr2In by Materials Project

Pr2In crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 6-coordinate geometry to eight Pr and six equivalent In atoms. There are two shorter (3.51 Å) and six longer (3.69 Å) Pr–Pr bond lengths. All Pr–In bond lengths are 3.69 Å. In the second Pr site, Pr is bonded to six equivalent Pr and five equivalent In atoms to form a mixture of distorted face and corner-sharing PrPr6In5 trigonal bipyramids. There are three shorter (3.24 Å) and two longer (3.51 Å) Pr–In bond lengths. In is bonded in a 11-coordinate geometry to eleven Pr atoms.
