The material structure described by MgMn2O4(MnO2)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two manganese;dihydrate molecules and one MgMn2O4 cluster. In the MgMn2O4 cluster, Mg(1) is bonded in a distorted linear geometry to two equivalent O(4) atoms. Mn(1) is bonded in a distorted linear geometry to one O(3) and one O(4) atom. There are two inequivalent O sites. In the first O site, O(4) is bonded in a 2-coordinate geometry to one Mg(1) and one Mn(1) atom. In the second O site, O(3) is bonded in a distorted single-bond geometry to one Mn(1) atom. is represented by the CIF file [CIF]
