K2Mn(PS3)2 crystallizes in the monoclinic P2_1/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. Mn(1) is bonded in a distorted octahedral geometry to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms. P(1) is bonded in a 3-coordinate geometry to one S(1), one S(2), and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded to three equivalent K(1), one Mn(1), and one P(1) atom to form a mixture of distorted corner and edge-sharing SK3MnP trigonal bipyramids. In the second S site, S(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one Mn(1), and one P(1) atom. In the third S site, S(3) is bonded in a 4-coordinate geometry to two equivalent K(1), one Mn(1), and one P(1) atom.
