Abstract
Tris(1-methylimidazolium) bis(1-methylimidazole)hexacosaoxidooctamolybdatesodium, (C4H7N2)3[NaMo8O26(C4H6N2)2], prepared from an aqueous solution containing Na2MoO4 and 1-methylimidazole, contains the novel chain-like anion ∞1[NaMo8O26(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(Nmim) octahedra. These molybdate units are interlinked by sodium, itself exhibiting a sixfold coordination with O atoms.
