Construction of Polyoxometalate-Based Inorganic–Organic Compounds Using Silver(I) Double Helicates as Secondary Building Blocks

Two polyoxometalate-based silver(I) compounds including a three-dimensional porous crystalline array and a double-helicate bisupporting cluster were achieved using metal–organic helicates and Keggin [PMo<sub>12</sub>O<sub>40</sub>]<sup>3–</sup> as secondary building blocks.
