Ni3Pb2S2 crystallizes in the trigonal R-3m space group. Ni(1) is bonded in a distorted linear geometry to two equivalent Pb(1), two equivalent Pb(2), and two equivalent S(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent Ni(1) and two equivalent S(1) atoms to form corner-sharing PbNi6S2 hexagonal bipyramids. In the second Pb site, Pb(2) is bonded in a distorted hexagonal planar geometry to six equivalent Ni(1) atoms. S(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) and one Pb(1) atom.
