wo polyoxometalate open framework (POMOF) materials have been synthesized using a secondary building unit (SBU) approach that facilitates the convergent assembly of multidimensional framework materials using a preassembled anionic SBU {P<sub>8</sub>W<sub>48</sub>}, with integrated "pore" 1 nm in diameter, and electrophilic manganese {Mn<sup>2+</sup>} linkers. This yields two new POMOFS with augmented hexagonal tiling (2 and 3), related to a known three-dimensional (3D) cubic array K<sub>18</sub>Li<sub>6</sub>[Mn<sup>II</sup><sub>8</sub>(H<sub>2</sub>O)<sub>48</sub>P<sub>8</sub>W<sub>48</sub>O<sub>184</sub>]·108H<sub>2</sub>O (1), K<sub>12</sub>[Mn<sup>II</sup>)<sub>14</sub>(H<sub>2</sub>O)<sub>30</sub>P<sub>8</sub>W<sub>48</sub>O<sub>184</sub>]·111H<sub>2</sub>O (2), and K<sub>8</sub>Li<sub>4</sub>[Mn<sup>II</sup>)<sub>14</sub>(H<sub>2</sub>O)<sub>26</sub>P<sub>8</sub>W<sub>48</sub>O<sub>184</sub>]·105H<sub>2</sub>O (3). These frameworks have been crystallized from aqueous Li-buffered solutions of {P<sub>8</sub>W<sub>48</sub>} and Mn<sup>II</sup>(ClO<sub>4</sub>))<sub>2</sub>·6H<sub>2</sub>O via careful control of the synthetic strategy akin to a crystal engineering approach using cation and temperature control to isolate different material architectures shown by compounds 1-3.
