The material structure described by Mn2GeO4 crystallizes in the orthorhombic Pbam space group. Mn(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Ge(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing GeO6 octahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Mn(1) and two equivalent Ge(1) atoms. In the second O site, O(1) is bonded to four equivalent Mn(1) and one Ge(1) atom to form a mixture of distorted edge and corner-sharing OMn4Ge trigonal bipyramids. is represented by the CIF card [CIF]
