Triazole based Ag coordination clusters: synthesis, structural diversity and anion exchange properties
In this work two new multi-dentate 1,2,4-triazole derivate ligands 4-(4-methyl-2-pyridine)-1,2,4-triazole (L 1 ), 4-(5-methyl-3-pyridine)-1,2,4-triazole (L 2 ) have been designed and synthesized. Three novel cluster-based cationic silver( i ) coordination compounds with L 1 and L 2 , namely [Ag 2 (H...
