[(C₂H₅)₄N]₄[Mo₈O₂₆]: a redetermination and correction

G. Kalpana and K. Vidyasagar

Abstract: The title compound, tetraethylammonium hexa-₃-oxo-hexa-₂-oxo-tetradecaoxooctamolybdate, contains discrete centrosymmetric -[Mo₈O₂₆]^4- anions and, for charge compensation, four tetraethylammonium cations per anion. The compound reported by Lu, Haung, Huang & Haung [(1989). Jiegou Huaxue, 8, 23-26] is evidently isostructural with the title compound, although Lu et al. formulated their phase as having a composition of {[(C₂H₅)₄N]⁺}₂·2H⁺·[Mo₈O₂₆]^4-.
