Pd3(PbSe)2 crystallizes in the trigonal R-3m space group. Pd(1) is bonded in a distorted linear geometry to two equivalent Pb(1), two equivalent Pb(2), and two equivalent Se(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent Pd(1) and two equivalent Se(1) atoms to form corner-sharing PbPd6Se2 hexagonal bipyramids. In the second Pb site, Pb(2) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(1) atoms. Se(1) is bonded in a 4-coordinate geometry to three equivalent Pd(1) and one Pb(1) atom.
