| Popis: | In the crystal structure of hexakis(2-methyl-1H-imidazol-3-ium) heptamolybdate 2-methyl-1H-imidazole disolvate dihydrate,(C4H7N2)6[Mo7O24]·2C4H6N2·2H2O, [Mo7O24]6− heptamolybdate anions, 2-methylimidazolium cations, neutral 2-methylimidazole molecules and water molecules are linked through hydrogen bonds into a three-dimensional network. The title compound, hexakis(2-methyl-1H-imidazol-3-ium) heptamolybdate 2-methyl-1H-imidazole disolvate dihydrate, (C4H7N2)6[Mo7O24]·2C4H6N2·2H2O, was prepared from 2-methylimidazole and ammonium heptamolybdate tetrahydrate in acid solution. The [Mo7O24]6− heptamolybdate cluster anion is accompanied by six protonated (C4H7N2)+ 2-methylimidazolium cations, two neutral C4H6N2 2-methylimidazole molecules and two water molecules of crystallization. The cluster consists of seven distorted MoO6 octahedra sharing edges or vertices. In the crystal, the components are linked by N—H⋯N, N—H⋯O, O—H⋯O, N—H⋯(O,O) and O—H⋯(O,O) hydrogen bonds, generating a three-dimensional network. Weak C—H⋯O interactions consolidate the packing. |
