The material described by K2SeO4.Te(OH)6 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(5), two equivalent O(2), and two equivalent O(4) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) and one O(5) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. In the third H site, H(3) is bonded in a distorted linear geometry to one O(1) and one O(4) atom. Te(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Se(1) is bonded in a tetrahedral geometry to two equivalent O(4) and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one K(1), one H(3), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), one H(2), and one Te(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one K(1), one H(1), and one Te(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent K(1), one H(3), and one Se(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(1), one H(1), and one Se(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
