The structure described by Mn(SeO3)2 crystallizes in the monoclinic P2_1/c space group. Mn(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Se(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Mn(1) and one Se(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mn(1) and one Se(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Mn(1) and one Se(1) atom. is represented by the CIF card [CIF]
