Abstract

Abstract: We synthesized a high‐nuclear isopolymolybdate cluster (n‐Bu4 N)6 H2 [{Mo24 O48 (OMe)32 }{Mo24 O52 (OMe)28 }2 ] ⋅ 25H2 O ⋅ 6CH3 CN (1) by using [Mo6 O19 ] 2− as the base precursor. Crystallographic characterization shows the cluster is composed of an anionic [{Mo24 O48 (OMe)32 }] 8− cage and two charge‐neutral [{Mo24 O52 (OMe)28 }] cages. Supported by the electrospray ionization mass spectrometry study, the polyoxoanion structural unit [Mo24 O48 (CH3 O)27 ] 3− demonstrates strong stability in acetonitrile solution. Moreover, 1 exhibits good proton conductivity of 1.79×10 −3 S cm −1 at 358 K and 98 % relative humidity.
