The structure described by KLaH2S2O9 crystallizes in the trigonal P3_221 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. La(1) is bonded in a 9-coordinate geometry to one O(5), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(5) atom. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one K(1), one La(1), and one S(1) atom. In the second O site, O(5) is bonded in a distorted water-like geometry to one La(1) and two equivalent H(1) atoms. In the third O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one La(1), and one S(1) atom. In the fourth O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one La(1), and one S(1) atom. In the fifth O site, O(3) is bonded in a distorted single-bond geometry to one K(1), one La(1), and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
