ThPb is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Th is bonded in a distorted body-centered cubic geometry to eight equivalent Pb atoms. All Th–Pb bond lengths are 3.44 Å. Pb is bonded in a body-centered cubic geometry to eight equivalent Th atoms.
ThPb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Th is bonded to twelve equivalent Pb atoms to form a mixture of face and corner-sharing ThPb12 cuboctahedra. All Th–Pb bond lengths are 3.48 Å. Pb is bonded in a distorted square co-planar geometry to four equivalent Th atoms.
ThPb crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Th is bonded in a 4-coordinate geometry to eight equivalent Pb atoms. There are four shorter (3.33 Å) and four longer (3.65 Å) Th–Pb bond lengths. Pb is bonded in a 4-coordinate geometry to eight equivalent Th atoms.
