Materials Data on TmPu3 by Materials Project
Pu3Tm is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pu sites. In the first Pu site, Pu is bonded to eight Pu and four equivalent Tm atoms to form PuTm4Pu8 cuboctahedra that share corners with twelve equivalent PuTm4Pu8 cuboctahedra, edges with eight equivalent TmPu12 cuboctahedra, edges with sixteen PuTm4Pu8 cuboctahedra, faces with four equivalent TmPu12 cuboctahedra, and faces with fourteen PuTm4Pu8 cuboctahedra. There are four shorter (3.39 Å) and four longer (3.40 Å) Pu–Pu bond lengths. All Pu–Tm bond lengths are 3.39 Å. In the second Pu site, Pu is bonded to eight equivalent Pu and four equivalent Tm atoms to form PuTm4Pu8 cuboctahedra that share corners with four equivalent PuTm4Pu8 cuboctahedra, corners with eight equivalent TmPu12 cuboctahedra, edges with twenty-four PuTm4Pu8 cuboctahedra, faces with six equivalent TmPu12 cuboctahedra, and faces with twelve PuTm4Pu8 cuboctahedra. All Pu–Tm bond lengths are 3.40 Å. Tm is bonded to twelve Pu atoms to form TmPu12 cuboctahedra that share corners with four equivalent TmPu12 cuboctahedra, corners with eight equivalent PuTm4Pu8 cuboctahedra, edges with eight equivalent TmPu12 cuboctahedra, edges with sixteen equivalent PuTm4Pu8 cuboctahedra, faces with four equivalent TmPu12 cuboctahedra, and faces with fourteen PuTm4Pu8 cuboctahedra.
