Summary, etc. The synthesis, single crystal structure, spectral, thermal and electrical properties of a hexarubidium heptamolybdate [Rb<sub>6</sub>(H<sub>2</sub>O)<sub>4</sub>(Mo<sub>7</sub>O<sub>24</sub>)]<strong> 1</strong> is reported. The bridging binding modes of the unique (Mo<sub>7</sub>O<sub>24</sub>)<sup>6-</sup> ion and the four crystallographically independent coordinated water molecules results in coordination numbers ranging from 8 to 10 for the six unique Rb(I) ions in <strong>1</strong>. Thermal decomposition of <strong>1</strong> results in the formation of an anhydrous residue of composition 7MoO<sub>3</sub>·3Rb<sub>2</sub>O. The cyclic voltammogram of an aqueous solution of <strong>1</strong> exhibits a single redox event characteristic of (Mo<sub>7</sub>O<sub>24</sub>)<sup>6-</sup> anion. Solution conductivity studies reveal the presence of hydrated Rb<sup>+</sup> cations and uncoordinated (Mo<sub>7</sub>O<sub>24</sub>)<sup>6- </sup>anions. A comparative study of several alkali-metal heptamolybdates reveals a rich structural chemistry in terms of the binding modes of the (Mo<sub>7</sub>O<sub>24</sub>)<sup>6-</sup> anion.
