The structure described by Pb3Te crystallizes in the hexagonal P6_3/mmc space group. Pb(1) is bonded to eight equivalent Pb(1) and four equivalent Te(1) atoms to form distorted PbTe4Pb8 cuboctahedra that share corners with four equivalent Te(1)Pb12 cuboctahedra, corners with fourteen equivalent Pb(1)Te4Pb8 cuboctahedra, edges with six equivalent Te(1)Pb12 cuboctahedra, edges with twelve equivalent Pb(1)Te4Pb8 cuboctahedra, faces with four equivalent Te(1)Pb12 cuboctahedra, and faces with sixteen equivalent Pb(1)Te4Pb8 cuboctahedra. Te(1) is bonded to twelve equivalent Pb(1) atoms to form distorted TePb12 cuboctahedra that share corners with six equivalent Te(1)Pb12 cuboctahedra, corners with twelve equivalent Pb(1)Te4Pb8 cuboctahedra, edges with eighteen equivalent Pb(1)Te4Pb8 cuboctahedra, faces with eight equivalent Te(1)Pb12 cuboctahedra, and faces with twelve equivalent Pb(1)Te4Pb8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
