Materials Data on MoPb by Materials Project
PbMo crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Mo is bonded to four equivalent Mo and eight equivalent Pb atoms to form distorted MoMo4Pb8 cuboctahedra that share corners with four equivalent MoMo4Pb8 cuboctahedra, corners with eight equivalent PbMo8Pb4 cuboctahedra, edges with eight equivalent PbMo8Pb4 cuboctahedra, edges with sixteen equivalent MoMo4Pb8 cuboctahedra, faces with eight equivalent MoMo4Pb8 cuboctahedra, and faces with ten equivalent PbMo8Pb4 cuboctahedra. All Mo–Mo bond lengths are 3.17 Å. There are four shorter (2.92 Å) and four longer (3.17 Å) Mo–Pb bond lengths. Pb is bonded to eight equivalent Mo and four equivalent Pb atoms to form distorted PbMo8Pb4 cuboctahedra that share corners with four equivalent PbMo8Pb4 cuboctahedra, corners with eight equivalent MoMo4Pb8 cuboctahedra, edges with eight equivalent MoMo4Pb8 cuboctahedra, edges with sixteen equivalent PbMo8Pb4 cuboctahedra, faces with eight equivalent PbMo8Pb4 cuboctahedra, and faces with ten equivalent MoMo4Pb8 cuboctahedra. All Pb–Pb bond lengths are 3.17 Å.
