摘要：
Three novel octamolybdates (emim)(3)K(Mo8O26) (1), (emim)(3)Rb(Mo8O26) (2) and (emim)(2)Cs-2(Mo8O26) (3) (emim = 1-ethyl-3-methylimidazolium) have been prepared by ionothermal reactions using (emim)Br as a solvent. The structures contain octamolybdate anions [beta-Mo8O26](4-). In compounds 1 and 2, [beta-Mo8O26](4-) units are linked by alkali metal cations to form 1D chain structures, while Cs cations in the compound 3 link to polyoxoanions to form a 2D layered structure.
