✦ Synopsis

The title double salt, K 2 Na 4 [V 10 O 28 ]Á18H 2 O, crystallizes with a decavanadate polyanion that has twofold crystallographic symmetry. All atoms in the structure are on general positions, except two Na atoms which are located on a twofold axis. In the crystal structure, chains made up of edge-and face-sharing [KO 9 ] and [NaO 6 ] polyhedra are interconnected by the decavanadate anions to form a three-dimensional network. The decavanadate polyanion exhibits the typical ranges in VÁ Á ÁV and the four types of V-O distances.
