The structure described by K2PbGe2S6 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 7-coordinate geometry to two equivalent S(2), two equivalent S(3), and three equivalent S(1) atoms. Pb(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(3) atoms. Ge(1) is bonded to one S(1), one S(3), and two equivalent S(2) atoms to form edge-sharing GeS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Pb(1), and one Ge(1) atom. In the second S site, S(2) is bonded to two equivalent K(1) and two equivalent Ge(1) atoms to form distorted edge-sharing SK2Ge2 trigonal pyramids. In the third S site, S(3) is bonded in a 1-coordinate geometry to two equivalent K(1), two equivalent Pb(1), and one Ge(1) atom. is represented by the CIF card [CIF]
