Hydrothermally prepared SrMn(SeO3)(2) contains infinite chains of vertex-sharing irregular MnO5+1 polyhedra [mean Mn-O 2.226 (3) Angstrom], which are fused into layers via pyramidal SeO3 groups [mean Se-O 1.698 (3) Angstrom]. Nine-coordinate Sr2+ cations [mean Sr-O 2.715 (4) Angstrom] complete the layered structure.
