We synthesized a high-nuclear isopolymolybdate cluster (n-Bu N) H [{Mo O (OMe) }{Mo O (OMe) } ] ⋅ 25H O ⋅ 6CH CN (1) by using [Mo O ] as the base precursor. Crystallographic characterization shows the cluster is composed of an anionic [{Mo O (OMe) }] cage and two charge-neutral [{Mo O (OMe) }] cages. Supported by the electrospray ionization mass spectrometry study, the polyoxoanion structural unit [Mo O (CH O) ] demonstrates strong stability in acetonitrile solution. Moreover, 1 exhibits good proton conductivity of 1.79×10 S cm at 358 K and 98 % relative humidity.
