Cluster Organic Frameworks Constructed from Heterometallic Supertetrahedral Cluster Secondary Building Units

Abstract

The two novel cluster organic frameworks based on heterometallic supertetrahedral cluster secondary building units (SBUs) [Cd₄Cu₆(L)₄(Ac)₇(H₂O)₄](Ac)·7H₂O (1) and [Mn₄Cu₆(L)₄(Ac)_4.5(H₂O)₉]CuCN(Ac)_3.5·H₂O (2), where H₃L = 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol and Ac = CH₃COO^-, 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.
