Abstract

The unique molybdenum-oxide capsule [{(Mo^VI)Mo^VI₅O₂₁(H₂O)₆}₁₂{Mo^V₂O₄(SO₄)}₃₀]⁷²⁻ shows an unprecedented affinity towards Ca²⁺ cations which interact in fully or partially hydrated forms with different well-defined internal and external receptor areas via direct coordination and/or hydrogen bonds. The cavity of the capsule comprises an unusual “water assembly” of the Ca₂₀{H₂O}₆₀ [triple bond, length as m-dash] Ca₂₀{(H₂O)₅}₁₂ type. Altogether, we can refer to a unique solid-state structure.
