The reactions of a series of nitrogen-containing heterocyclic thioether ligands, 2, 2′- [methylenebis (thio)] bis (pyrimidine)(L1), 2, 2′-[1, 2-ethanediylbis (thio)] bis (pyrimidine)(L2), 2, 2′-[methylenebis (thio)] bis [5-methyl-1, 3, 4-thiadiazole](L3) and 2, 2′- [1, 2-ethanediylbis (thio)] bis [5-methyl-1, 3, 4-thiadiazole](L4), with silver (I) nitrate or silver (I) perchlorate salt led to the formation of five new metal–organic supramolecular ...
