Formation of one of the most representative polyoxometalate (POM) archetypes, namely the Lindqvist anion M 6 O 19 2- with M = Mo VI or W VI , was considered as elusive in aqueous solution. Herein, we report on the host-guest stabilization of the M 6 O 19 2- species with M = Mo or W from aqueous solution using γ-cyclodextrin as trapping agent. The adduct {M 6 O 19 @γ-CD} 2- reveals remarkable hydrolytic stability that offers new opportunities for exploring potentialities of molybdates or tungstates in the field of biology and medicine, when combined to CDs as efficient drug carrier/delivery agents.
