K3NaS2 crystallizes in the hexagonal P-6m2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. In the second K site, K(2) is bonded in a distorted trigonal planar geometry to two equivalent S(1) and three equivalent S(2) atoms. Na(1) is bonded in a trigonal planar geometry to three equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 11-coordinate geometry to two equivalent K(2), six equivalent K(1), and three equivalent Na(1) atoms. In the second S site, S(2) is bonded in a 9-coordinate geometry to three equivalent K(2) and six equivalent K(1) atoms.
