The crystal structure of dicalcium bis(oxonium) decavanadate hexadecahydrate has been determined by X-ray analysis. The main feature of the structure is the [V10O28]6- anion, built up from ten distorted edge-sharing VO6 octahedra with well established structures. Each Ca2+ ion is surrounded by seven water molecules in the form of a distorted pentagonal bipyramid.
