An extended framework of cages formed of pre-synthesised and functionalised heterometallic cages

Abstract

We present the first example of an extended 3D framework synthesised without the use of an isolable organic component. This is achieved by the combination of two cage complexes isolated and functionalised prior to synthesis; [ⁿPr₂NH₂][Cr₇NiF₈(O₂C^tBu)₁₄(O₂CC₅H₄N)₂] and [Fe₂CoO(O₂C^tBu)₆(HO₂C^tBu)₃], where the former is as a bidentate linker, bridging between three nodes of the latter.
