Synthesis and response towards heating and UV irradiation of two novel zinc(II) cyclobutane-1,1′-dicarboxylate complexes were examined using X-ray diffraction, FT-IR and 1H NMR spectroscopy. One of the complexes underwent a photoinitiated solid state transformation of 1,2-bis(pyrid-4-yl)ethylene into 1,2,3,4-tetrakis(pyrid-4-yl)cyclobutane. A preliminary dehydration of this solid decreases the conversion rate of photoreaction.
