(Ca3Mn(SO7)2)2(H2)3 crystallizes in the hexagonal P6_3/mmc space group. The structure consists of six 1333-74-0 atoms inside a Ca3Mn(SO7)2 framework. In the Ca3Mn(SO7)2 framework, Ca(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form distorted CaO6 pentagonal pyramids that share corners with two equivalent S(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with two equivalent Ca(1)O6 pentagonal pyramids. Mn(1) is bonded to six equivalent O(2) atoms to form MnO6 octahedra that share edges with six equivalent Ca(1)O6 pentagonal pyramids. S(1) is bonded to one O(1) and three equivalent O(3) atoms to form SO4 tetrahedra that share corners with three equivalent Ca(1)O6 pentagonal pyramids. There are three inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one Ca(1) and one S(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to one S(1) atom. In the third O site, O(2) is bonded in a trigonal non-coplanar geometry to two equivalent Ca(1) and one Mn(1) atom.
