Tris(1-methylimidazolium) bis(1-methylimidazole)hexacosaoxidooctamolybdatesodium, (C(4)H(7)N(2))(3)[NaMo(8)O(26)(C(4)H(6)N(2))(2)], prepared from an aqueous solution containing Na(2)MoO(4) and 1-methylimidazole, contains the novel chain-like anion (infinity)(1)NaMo(8)O(26)(mim)(2) (mim is 1-methylimidazole). The Mo(8)O(26)(mim)(2) building unit, which lies across a center of inversion, is comprised of eight edge-sharing MoO(6) and MoO(5)(N(mim)) octahedra. These molybdate units are interlinked by sodium, itself exhibiting a sixfold coordination with O atoms.
由含有钼酸钠和1-甲基咪唑的水溶液制备的三（1-甲基咪唑鎓）双（1-甲基咪唑）二十六氧化八钼酸钠，（C₄H₇N₂）₃[NaMo₈O₂₆（C₄H₆N₂）₂]，包含新型链状阴离子（∞）₁[NaMo₈O₂₆（mim）₂]³⁻（mim为1-甲基咪唑）。跨越一个反演中心的[Mo₈O₂₆（mim）₂]⁴⁻结构单元由八个共边的MoO₆和MoO₅（N（mim））八面体组成。这些钼酸盐单元通过钠相互连接，钠本身与氧原子呈现六重配位。
