title: Tetra-potassium cis-dioxido-trans-bis-(sulfato-κO)sulfato(κO,O')molybdate(VI).
abstract: The title compound, K(4)[Mo(VI)O(2)(SO(4))(3)], was precipitated from a melt of molybdenum(VI) oxide and potassium sulfate in potassium disulfate. The compound contains monomeric [Mo(VI)O(2)(SO(4))(3)](4-) anions, with the Mo(VI) atom, both oxide ligands, and the S atom and both ligating O atoms of the bidentate sulfate group lying on a crystallographic mirror plane. One of the potassium cations is nine-coordinate, while the other is eight-coordinate.
