The compound described by Mn(GeO3)2 crystallizes in the monoclinic C2/c space group. Mn(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent Mn(1)O6 octahedra. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Mn(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 37-64°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to two equivalent Mn(1) and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
