The hydrothermal reaction of [H2W12O42](10) precursors and CuCl2 in a CH3COOK/CH3COOH solution (pH 3.5) led to the isolation of a new compound, KNa3[Cu(H2O)(2){Cu(H2O)(3)}(2)(H2W12O42)] center dot 16H(2)O (1). Compound 1 possesses a new anionic three-dimensional (3-D) open-framework based on the [H2W12O42](10) building blocks and Cu-II linkers. This anionic 3-D framework represents the. first example of a (8,3)-connected structural topology in POM-based solid materials. The magnetic behavior of 1 exhibits weak antiferromagnetic interaction.
