K3MoHS4O crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 1-coordinate geometry to two equivalent S(1), two equivalent S(2), and one O(1) atom. In the second K site, K(2) is bonded in a 8-coordinate geometry to one H(1), two equivalent S(3), four equivalent S(1), and one O(1) atom. Mo(1) is bonded in a distorted tetrahedral geometry to one S(2), two equivalent S(1), and one O(1) atom. H(1) is bonded in a single-bond geometry to one K(2) and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Mo(1) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Mo(1) atom. In the third S site, S(3) is bonded in a distorted single-bond geometry to two equivalent K(2) and one H(1) atom. O(1) is bonded in a distorted trigonal pyramidal geometry to one K(2), two equivalent K(1), and one Mo(1) atom.
