AgPbSbS3 crystallizes in the monoclinic P2_1/c space group. Ag(1) is bonded in a 5-coordinate geometry to two equivalent S(3) and three equivalent S(1) atoms. Pb(1) is bonded to one S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of corner and edge-sharing PbS6 octahedra. The corner-sharing octahedral tilt angles range from 12-20°. Sb(1) is bonded in a 4-coordinate geometry to one S(3), two equivalent S(1), and two equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to three equivalent Ag(1), one Pb(1), and two equivalent Sb(1) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Pb(1) and two equivalent Sb(1) atoms. In the third S site, S(3) is bonded to two equivalent Ag(1), two equivalent Pb(1), and one Sb(1) atom to form distorted edge-sharing SAg2SbPb2 square pyramids.
