Single‐Crystal‐to‐Single‐Crystal Transformations of Two Three‐Dimensional Coordination Polymers through Regioselective [2+2] Photodimerization Reactions

Abstract

The crystal method: Single-crystal-to-single-crystal (SCSC) transformations of two 3D coordination polymers, {[Zn4(μ3-OH)2(5-sipa)2(1,4-bpeb)2]⋅4 H2O}n (see picture; C pale blue, N dark blue, H green) and an analogous cadmium species, gave rise to corresponding linked 3D coordination polymers through photochemical [2+2] cycloaddition reactions.
