Abstract

The nitrile-functionalized derivatives of 2,8-dithia-5-aza-2,6-pyridinophane ([12]anePyNS2)(Py = Pyridine), 1-aza-4,7,10-trithiacyclododecane ([12]aneNS3), and N,N’-bis(2-pyridylmethyl)-propylenediamine (Pypn), referred to as L10, L11 and L12, respectively, have been prepared. Following the reaction of these ligands with silver(I) salts, the three coordination polymers (CPs) {[Ag(L10)](BF4)}∞, {[Ag(L11)](BF4)∙½MeCN}∞, and {[Ag(L12)](NO3)}∞, have been isolated and structurally characterized. The structural features of the three CPs depends more on the nature of the un-functionalized ligands rather than on the presence of the nitrile groups. A comparative analysis of the structures of the three CPs is performed in relation to the structures of polymeric silver(I) compounds obtained with nitrile-functionalized pendant arms of related aza- and mixed donor macrocyclic ligands (L1–L9) reported in the literature.
