In₂Ge₆O₁₅(OH)₂(H ₂dien): An open-framework indate germanate with one-dimensional 12-ring channels

A microporous indate germanate, prepared under mild solvothermal conditions with an organic amine as structure-directing agent, has a structure in which germanate layers (green) are linked by cis-edge-sharing chains of In-O octahedra (pink) to form a framework with 1D 12-ring channels (see picture).
