The crystal structure described by KVH2SeO7 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(5), one O(7), two equivalent O(3), and two equivalent O(6) atoms. V(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(7) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(4) atom. Se(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(5), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted water-like geometry to one V(1), one H(1), and one H(2) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to one K(1) and one Se(1) atom. In the third O site, O(6) is bonded in a distorted single-bond geometry to two equivalent K(1) and one V(1) atom. In the fourth O site, O(7) is bonded in a distorted bent 120 degrees geometry to one K(1), one V(1), and one Se(1) atom. In the fifth O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one V(1), and one Se(1) atom. In the sixth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one K(1), one V(1), and one Se(1) atom. In the seventh O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one V(1) atom. is represented by the CIF card [CIF]
