Materials Data on Pm3Tl by Materials Project
Pm3Tl is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pm is bonded to eight equivalent Pm and four equivalent Tl atoms to form distorted PmPm8Tl4 cuboctahedra that share corners with twelve equivalent PmPm8Tl4 cuboctahedra, edges with eight equivalent TlPm12 cuboctahedra, edges with sixteen equivalent PmPm8Tl4 cuboctahedra, faces with four equivalent TlPm12 cuboctahedra, and faces with fourteen equivalent PmPm8Tl4 cuboctahedra. All Pm–Pm bond lengths are 3.51 Å. All Pm–Tl bond lengths are 3.51 Å. Tl is bonded to twelve equivalent Pm atoms to form TlPm12 cuboctahedra that share corners with twelve equivalent TlPm12 cuboctahedra, edges with twenty-four equivalent PmPm8Tl4 cuboctahedra, faces with six equivalent TlPm12 cuboctahedra, and faces with twelve equivalent PmPm8Tl4 cuboctahedra.
