Construction of Two High‐Nuclear 3d‐4d Heterometallic Cluster Organic Frameworks by Introducing a Bifunctional Tripodal Alcohol as a Structure‐Directing Agent.

Two unique heterometallic cluster organic frameworks, [Cd4MnIII4MnII6(Tri)4(CH3COO)14(μ4‐O)2(μ3‐O)2(H2O)2] Cd(H2O)2⋅9 H2O (1) and Cu[Cd5Cu6(Tri)4(CH3COO)9(H2O)4]2(CH3COO)3⋅24 H2O (2) (H3Tri=2‐(hydroxymethyl)‐2‐(pyridine‐4‐yl)‐1,3‐propanediol), have been successfully prepared by employing a bifunctional tripodal alcohol ligand as a structure‐directing agent. Crystal structure analyses reveal that 1 represents a rare example of frameworks constructed from Cd−Mn heterometallic chains, and 2 is the first heterometallic MOF based on highest‐nuclear Cd−Cu heterometallic cluster building blocks. Furthermore, the magnetic properties and gas adsorption abilities of 1 and 2 were systematically studied. [ABSTRACT FROM AUTHOR]
