Materials Data on NaPm3 by Materials Project
NaPm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na is bonded to twelve equivalent Pm atoms to form NaPm12 cuboctahedra that share corners with twelve equivalent NaPm12 cuboctahedra, edges with twenty-four equivalent PmNa4Pm8 cuboctahedra, faces with six equivalent NaPm12 cuboctahedra, and faces with twelve equivalent PmNa4Pm8 cuboctahedra. All Na–Pm bond lengths are 3.64 Å. Pm is bonded to four equivalent Na and eight equivalent Pm atoms to form PmNa4Pm8 cuboctahedra that share corners with twelve equivalent PmNa4Pm8 cuboctahedra, edges with eight equivalent NaPm12 cuboctahedra, edges with sixteen equivalent PmNa4Pm8 cuboctahedra, faces with four equivalent NaPm12 cuboctahedra, and faces with fourteen equivalent PmNa4Pm8 cuboctahedra. All Pm–Pm bond lengths are 3.64 Å.
