Molecular recognition of Ca2+ cations by internal and external receptors/interfaces in a spherical porous molybdenum-oxide capsule: unusual coordination scenarios

Author affiliations

Abstract

The unique molybdenum-oxide capsule [{(MoVI)MoVI5O21(H2O)6}12{MoV2O4(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.
