Pd2PbBi crystallizes in the monoclinic Cm space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 10-coordinate geometry to one Pd(2), two equivalent Pd(3), one Pb(2), two equivalent Pb(1), and four equivalent Bi(1) atoms. In the second Pd site, Pd(2) is bonded in a 10-coordinate geometry to one Pd(1), two equivalent Pd(3), one Pb(1), two equivalent Pb(2), and four equivalent Bi(1) atoms. In the third Pd site, Pd(3) is bonded in a 9-coordinate geometry to one Pd(1), one Pd(2), two equivalent Pb(1), two equivalent Pb(2), and three equivalent Bi(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one Pd(2), two equivalent Pd(1), and four equivalent Pd(3) atoms. In the second Pb site, Pb(2) is bonded in a 7-coordinate geometry to one Pd(1), two equivalent Pd(2), and four equivalent Pd(3) atoms. Bi(1) is bonded in a 7-coordinate geometry to two equivalent Pd(1), two equivalent Pd(2), and three equivalent Pd(3) atoms.
