Materials Data on LaThPb6 by Materials Project
ThLaPb6 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Th is bonded to twelve Pb atoms to form ThPb12 cuboctahedra that share corners with four equivalent ThPb12 cuboctahedra, corners with eight equivalent LaPb12 cuboctahedra, faces with two equivalent LaPb12 cuboctahedra, and faces with four equivalent ThPb12 cuboctahedra. There are four shorter (3.48 Å) and eight longer (3.51 Å) Th–Pb bond lengths. La is bonded to twelve Pb atoms to form LaPb12 cuboctahedra that share corners with four equivalent LaPb12 cuboctahedra, corners with eight equivalent ThPb12 cuboctahedra, faces with two equivalent ThPb12 cuboctahedra, and faces with four equivalent LaPb12 cuboctahedra. There are four shorter (3.48 Å) and eight longer (3.54 Å) La–Pb bond lengths. There are three inequivalent Pb sites. In the first Pb site, Pb is bonded in a square co-planar geometry to four equivalent La atoms. In the second Pb site, Pb is bonded in a distorted square co-planar geometry to four equivalent Th atoms. In the third Pb site, Pb is bonded in a distorted square co-planar geometry to two equivalent Th and two equivalent La atoms.
