Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Two solid‐state structural transformations that occur in a stepwise and a controlled manner are described. A combination of desolvation and cycloaddition reactions has been employed to synthesise a 3D coordination polymer (CP) from 1D CP [Cd(bdc)(4‐spy)₂(H₂O)]⋅2 H₂O⋅2 DMF (bdc=1, 4‐benzenedicarboxylate, 4‐spy=4‐styrylpyridine) presumably via a 2D layered structure, [Cd₂(bdc)₂(4‐spy)₄]. In the absence of single crystals to follow the course of the photocycloaddition reaction, thermogravimetry, XAFS and NOESY NMR experiments were used to propose the formation of layered and pillared layered structures. Further, the present strategy enables us to synthesise new multidimensional architectures that are otherwise inaccessible by the self‐assembly process.</p> </abstract>
