The structure described by K2LiNbO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), and two equivalent O(4) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(1) atoms. Li(1) is bonded in a distorted trigonal planar geometry to one O(1), one O(2), and two equivalent O(3) atoms. Nb(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one K(1), two equivalent K(2), one Li(1), and one Nb(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Li(1), and one Nb(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one K(1), one K(2), two equivalent Li(1), and one Nb(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one Nb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
