Abstract

Four silver-based coordination polymers, {[Ag(L1)2]NO3}∞ (1), {[Ag(L1)2]ClO4}∞ (2), {[Ag(L2)2]NO3·H2O}∞ (3) and {[Ag(L2)2]ClO4}∞ (4), were synthesized using the thiomorpholine-4-carbonitrile (L1) and piperazine-1,4-dicarbonitrile (L2) ligands. Compounds 1 and 2 are two-dimensional, while 3 and 4 are three-dimensional. L1 and L2 are 1,4-bis-monodentate ligands in all compounds, while Ag(I) ions are four-coordinated in a slightly distorted tetrahedral geometry. The supplementary ifnormation contains: Selected hydrogen-bond parameters for 3, solid-state optical absorption spectra for crystalline samples of 1–4, plots of concentration ratios against irradiation time for 1–4 and Degussa P25, the changes in photodegradation percentage of MB9 after three successive cycles for 4, IR spectra of pristine and CP 4 after the third cycle and UV–vis spectra for the MB9 solution in the presence of 4 and quenchers. CCDC numbers are 2068533–2068536 for compounds 1–4, respectively.
