The
coordination polymers (CPs) of bis(3-pyridyl-acrylamido)ethane
(<b>L</b>) with nitrate, acetate, and perchlorate salts of Cu(II),
Cd(II), and Zn(II) were synthesized, and their crystal structures
have been analyzed with respect to the influence of anions, hydrogen
bonding, and their solid state [2 + 2] photochemical reactivity. Four
out of the six CPs (<b>1</b>–<b>4</b>) containing
NO<sub>3</sub><sup>–</sup> and AcO<sup>–</sup> ions
were found to form one-dimensional chains and exhibit solid state
[2 + 2] reactivity. Two CPs (<b>5</b>–<b>6</b>)
containing ClO<sub>4</sub><sup>–</sup> ions were found to form
M<b>L</b><sub><b>2</b></sub> discrete complexes which
are photostable. The CPs <b>1</b> and <b>4</b> were found
to form single [2 + 2] dimers, while <b>2</b> and <b>3</b> resulted in the formation of polymers via solid state [2 + 2] polymerization
upon irradiation. The photoproducts are characterized by <sup>1</sup>H NMR, electrospray ionization mass spectrometry, and matrix-assisted
laser desorption/ionization–time of flight (MALDI-TOF) spectra.
The dimer was charecterized by single crystal X-ray structure determination.
The MALDI-TOF analyses of polymers indicate the highest degree (29-mer)
of polymerization.
