Pd3Bi2S2 crystallizes in the monoclinic C2/m space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. In the third Pd site, Pd(3) is bonded in a 2-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to two equivalent Pd(1), two equivalent Pd(2), and two equivalent Pd(3) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to two equivalent Pd(1), two equivalent Pd(2), and two equivalent Pd(3) atoms. S(1) is bonded in a distorted T-shaped geometry to one Pd(1), one Pd(2), and one Pd(3) atom.
