| description | Polyoxometalate (POM)-type supramolecular materials have unique structures and hold immense potential for development in the fields of biomedicine, information storage, and electrocatalysis. In this study, (NH<sub>4</sub>)<sub>3</sub> [AlMo<sub>6</sub>O<sub>24</sub>H<sub>6</sub>]·7H<sub>2</sub>O was employed as a polyacid anion template, pentacyclic imidazole molecules served as organic ligands, and the moderate-temperature hydrothermal and natural evaporation methods were used in combination for the design and synthesis of two octamolybdenum-oxo cluster (homopolyacids containing molybdenum-oxygen structures as the main small-molecular structures)-based organic–inorganic hybrid compounds, [(C<sub>3</sub>N<sub>2</sub>H<sub>5</sub>)(C<sub>3</sub>N<sub>2</sub>H<sub>4</sub>)][(<i>β</i>-Mo<sub>8</sub>O<sub>26</sub>H<sub>2</sub>)]<sub>0.5</sub> (<b>1</b>) and {Zn(C<sub>3</sub>N<sub>2</sub>H<sub>4</sub>)<sub>4</sub>}{[(<i>γ</i>-Mo<sub>8</sub>O<sub>26</sub>)(C<sub>3</sub>N<sub>2</sub>H<sub>4</sub>)<sub>2</sub>]<sub>0.5</sub>}·2H<sub>2</sub>O (<b>2</b>). Structural and property characterization revealed that both compounds crystallized in the <i>P</i>-1 space group with relatively stable three-dimensional structures under the action of hydrogen bonding. Upon temperature stimulation, the [Zn(C<sub>3</sub>N<sub>2</sub>H<sub>4</sub>)<sub>4</sub>]<sup>2+</sup> cation and water molecules in <b>2</b> exhibited obvious oscillations, leading to significant dielectric anomalies at approximately 250 and 260 K when dielectric testing was conducted under heating conditions. |
