Only corner‐sharing between the seven TaO 6 octahedra is observed in the neutral complex [H −11 Ta 7 O 12 (tdci) 6 ] (tdci = 1,3,5‐trideoxy‐1,3,5‐tris(dimethylamino)‐ cis ‐inositol). The structure on the right (only one tdci ligand is illustrated) depicts the Ta 7 O 30 double adamantane core. In contrast to previously described structures of polyoxometalate ions, which have a predominantly edge‐shared framework, this compound has an unusually open structure.
