The novel chain‐like anion ∞1[NaMo8O26(mim)2]3− in (Hmim)3[NaMo8O26(mim)2] (mim is 1‐methylimidazole)

Tris(1‐methylimidazolium) bis(1‐methylimidazole)hexacosaoxidooctamolybdatesodium, (C₄H₇N₂)₃NaMo₈O₂₆(C₄H₆N₂)₂], prepared from an aqueous solution containing Na₂MoO₄ and 1‐methylimidazole, contains the novel chain‐like anion _∞¹NaMo₈O₂₆(mim)₂]^{3 −} (mim is 1‐methylimidazole). The Mo₈O₂₆(mim)₂]⁴⁻ building unit, which lies across a center of inversion, is comprised of eight edge‐sharing MoO₆ and MoO₅(N_mim) octahedra. These molybdate units are interlinked by sodium, itself exhibiting a sixfold coordination with O atoms.
