The crystal structure described by K2Mn(SeO3)2 crystallizes in the trigonal R-3m space group. K(1) is bonded in a 10-coordinate geometry to one Se(1) and nine equivalent O(1) atoms. Mn(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one K(1) and three equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Mn(1), and one Se(1) atom. is represented by the CIF file [CIF]
