Abstract

A new ammonium magnesium paradodecatungstate decahydrate, namely diammonium octadecaaquahydrogentetramagnesiododecatungstate decahydrate, (NH₄)₂-[Mg₄(H₂O)₁₈(H ₂W₁₂O₄₂)]·10H₂O, was prepared by the reaction of (NH₄)₁₀[H₂W₁₂O ₄₂]·4H₂O with MgCl₂ in aqueous solution. The skeleton of the paradodecatungstate ion, [H₂W₁₂O₄₂]^10-, is basically the same as those in the known paradodecatungstates. It consists of 12 interconnected WO₆ octahedra and its centre is located at a crystallographic inversion centre. Both independent Mg atoms are octahedrally coordinated by six O atoms. One magnesium octahedron shares an O atom with a paradodecatungstate group and the other magnesium octahedron shares two O atoms, each with different paradodecatungstate groups, to form a one-dimensional [Mg₄(H₂O)₁₈(H₂W₁₂O ₄₂)]^2n- _n chain along the b direction.
