DOIAbstract
Two new ε-Keggin-type polyoxometalate-based 3D frameworks, Na<sub>1.5</sub>H<sub>11.4</sub>[ε-Zn<sup>II</sup>Mo<sup>V</sup><sub>10.9</sub>Mo<sup>VI</sup><sub>1.1</sub>O<sub>40</sub>{Zn<sup>II</sup>}<sub>2</sub>] and (NH<sub>4</sub>)<sub>2.1</sub>H<sub>7.5</sub>[ε-Mn<sup>II</sup><sub>0.2</sub>Mo<sup>V</sup><sub>6</sub>Mo<sup>VI</sup><sub>6</sub>O<sub>40</sub>{Mn<sup>II</sup>}<sub>2</sub>], are prepared, and their structures are determined by powder X-ray diffraction, Fourier transform infrared, Raman spectroscopy, and elemental analysis. ε-Keggin-type polyoxomolybdate units, [ε-ZnMo<sub>12</sub>O<sub>40</sub>] and [ε-Mn<sub>0.2</sub>Mo<sub>12</sub>O<sub>40</sub>], are linked with Zn<sup>2+</sup> and Mn<sup>2+</sup>, respectively, in a tetrah...
