The structure described by PtPb3Bi crystallizes in the tetragonal P4_2/mnm space group. Pt(1) is bonded in a 9-coordinate geometry to one Pt(1), two equivalent Pb(1), four equivalent Pb(2), and two equivalent Bi(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 10-coordinate geometry to one Pt(1), two equivalent Pb(2), four equivalent Pb(1), and three equivalent Bi(1) atoms. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to four equivalent Pt(1) and four equivalent Pb(1) atoms. Bi(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1) and six equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
