Popis:	The title compound is a new mixed alkali/3d metal phosphite. It exhibits a layered structure formed by linear Mn3O12 trimer units which contain face-sharing MnO6 octa­hedra inter­connected by (HPO3)2− phosphite oxoanions. The K+ cations located between the anionic [Mn3(HPO3)4]2− sheets are ninefold coordinated. The presence of the alkaline ion leads to the highest symmetry and shortest inter­layer distance compared with two previous compounds showing the same anionic framework and having ammonium salts as cations. The compound crystallizes in the space group R\overline{3}m, with two crystallographically independent Mn atoms occupying sites of \overline{3}m and 3m symmetry. All the other atoms, except for the phosphite O atoms, are located on special positions with 3m symmetry.
