The material structure described by Yb2Au2Pb crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 10-coordinate geometry to six equivalent Au(1) and four equivalent Pb(1) atoms. In the second Yb site, Yb(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Pb(1) atoms. Au(1) is bonded in a 6-coordinate geometry to three equivalent Yb(1), three equivalent Yb(2), and two equivalent Pb(1) atoms. Pb(1) is bonded to four equivalent Yb(1), four equivalent Yb(2), and four equivalent Au(1) atoms to form a mixture of face and corner-sharing PbYb8Au4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
