Materials Data on Pm3Pr by Materials Project
Pm3Pr is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pm sites. In the first Pm site, Pm is bonded to eight Pm and four equivalent Pr atoms to form PmPm8Pr4 cuboctahedra that share corners with twelve equivalent PmPm8Pr4 cuboctahedra, edges with eight equivalent PrPm12 cuboctahedra, edges with sixteen PmPm8Pr4 cuboctahedra, faces with four equivalent PrPm12 cuboctahedra, and faces with fourteen PmPm8Pr4 cuboctahedra. There are four shorter (3.67 Å) and four longer (3.68 Å) Pm–Pm bond lengths. All Pm–Pr bond lengths are 3.68 Å. In the second Pm site, Pm is bonded to eight equivalent Pm and four equivalent Pr atoms to form PmPm8Pr4 cuboctahedra that share corners with four equivalent PmPm8Pr4 cuboctahedra, corners with eight equivalent PrPm12 cuboctahedra, edges with twenty-four PmPm8Pr4 cuboctahedra, faces with six equivalent PrPm12 cuboctahedra, and faces with twelve PmPm8Pr4 cuboctahedra. All Pm–Pr bond lengths are 3.67 Å. Pr is bonded to twelve Pm atoms to form PrPm12 cuboctahedra that share corners with four equivalent PrPm12 cuboctahedra, corners with eight equivalent PmPm8Pr4 cuboctahedra, edges with eight equivalent PrPm12 cuboctahedra, edges with sixteen equivalent PmPm8Pr4 cuboctahedra, faces with four equivalent PrPm12 cuboctahedra, and faces with fourteen PmPm8Pr4 cuboctahedra.
