KLiMnO2 crystallizes in the orthorhombic Cccm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with four equivalent Mn(1)O4 tetrahedra,  an edgeedge with one Li(1)O4 tetrahedra, and edges with two equivalent Mn(1)O4 tetrahedra. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with two equivalent Mn(1)O4 tetrahedra, corners with four equivalent Li(1)O4 tetrahedra,  an edgeedge with one Mn(1)O4 tetrahedra, and edges with two equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), two equivalent Li(1), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 7-coordinate geometry to one K(1), two equivalent K(2), two equivalent Li(1), and two equivalent Mn(1) atoms.
