The structure described by K3AsS3 crystallizes in the cubic P2_13 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. In the third K site, K(3) is bonded to six equivalent S(1) atoms to form distorted corner-sharing KS6 octahedra. The corner-sharing octahedral tilt angles are 64°. As(1) is bonded in a trigonal non-coplanar geometry to three equivalent S(1) atoms. S(1) is bonded to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one As(1) atom to form a mixture of distorted corner, edge, and face-sharing SK6As pentagonal bipyramids. is represented by the CIF card [CIF]
