The structure described by K4MoO8 crystallizes in the triclinic P1 space group. There are four inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(6), one O(7), and one O(8) atom. In the second K site, K(2) is bonded in a 4-coordinate geometry to one O(1), one O(3), one O(5), one O(6), and one O(8) atom. In the third K site, K(3) is bonded in a 2-coordinate geometry to one O(5), one O(6), and two equivalent O(8) atoms. In the fourth K site, K(4) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. Mo(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded to one K(1), one K(2), one K(4), and one O(4) atom to form distorted corner-sharing OK3O trigonal pyramids. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1), one K(4), and one Mo(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one K(1), one K(2), one K(4), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one K(4), one O(1), and one O(5) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one K(2), one K(3), one K(4), and one O(4) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one K(1), one K(2), one K(3), one K(4), and one Mo(1) atom. In the seventh O site, O(7) is bonded in a 4-coordinate geometry to one K(1), one K(4), one Mo(1), and one O(8) atom. In the eighth O site, O(8) is bonded to one K(1), one K(2), one K(4), two equivalent K(3), one Mo(1), and one O(7) atom to form distorted OK5MoO pentagonal bipyramids that share corners with two equivalent O(8)K5MoO pentagonal bipyramids and corners with three equivalent O(1)K3O trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
