Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>One‐dimensional coordination polymers (CPs)</bold> containing ladder structures are ideal to conduct [2+2] cycloaddition reactions. While attempting to align the bis(4′‐pyridyl)ethylene ligand pairs using Pb^II and three different benzoate anions, linear photostable CPs were obtained with a hydrogen‐bonded water chain in the lattice as a kinetic product. On removal of the lattice water, the polymers rearrange to a ladder structure. One of the three ladder structures synthesized undergoes a single‐crystal‐to‐single‐crystal photochemical reaction to give the cyclobutane‐containing coordination polymer as described in the Full Paper by J.
