The structure described by K(FeO4)3(H2)3(SO)2 crystallizes in the trigonal R-3m space group. The structure consists of nine 1333-74-0 molecules and six sulfur monoxide molecules inside a K(FeO4)3 framework. In the K(FeO4)3 framework, K(1) is bonded in a 6-coordinate geometry to six equivalent O(3) atoms. Fe(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. There are two inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one Fe(1), and one O(2) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Fe(1) and one O(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
