Cluster Organic Frameworks Constructed from Heterometallic Supertetrahedral Cluster Secondary Building Units.

The two novel cluster organic frameworks based on heterometallic supertetrahedral cluster secondary building units (SBUs) [Cd4 Cu6 (L)4 (Ac)7 (H2 O)4 ](Ac)·7H2 O (1) and [Mn4 Cu6 (L)4 (Ac)4.5 (H2 O)9 ]CuCN(Ac)3.5 ·H2 O (2), where H3 L = 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol and Ac = CH3 COO- , have been prepared under solvothermal conditions. 1 and 2 are the first cases of cluster organic frameworks containing Cd-Cu/Mn-Cu heterometallic supertetrahedral cluster SBUs. Furthermore, 1 and 2 show an integration of magnetic properties and adsorption properties from both the heterometallic cluster secondary building units and the framework in a porous material.
