Elucidating the Structure of the Metal-Organic Framework Ru-HKUST-1.

ABSTRACT: Ru-HKUST-1 (Ru3(btc)2X1.5;btc3-=1,3,5-benzenetricarboxylate; X-=chloride,acetate,trimesate,hydroxide) has received considerable attention as a result of its structure type, tunability, and the redox-active nature of its constituent metal paddlewheel building units. As compared to some of the other members of the HKUST-1 family, its surface area is typically reported as ~25% lower than expected. In contrast to this, a related ruthenium-based porous coordination cage, Ru24(tBu-bdc)24Cl12, displays the expected surface area when compared to Cr2+ and Mo2+ analogs. Here, we examine the factors that result in this decreased surface area for the MOF. We show that with appropriate solvent exchange and activation conditions, Ru-HKUST-1 can display a B.E.T. surface areas as high as 1439 m²
