| Abstract: | Bis(5-methyl-2-(2,3-diaza-4-(5-methyl-2-thienyl)buta-1,3-dienyl)thiophene) silver(I) complex was synthesized in high yield by refluxing 5-methyl-2-(2,3-diaza-4-(5-methyl-2-thienyl)buta-1,3-dienyl)thiophene (L) with silver nitrate or silver perchlorate in anhydrous acetonitrile. The product thus formed was well characterized by NMR, IR, UV–Vis and mass spectroscopies as well as elemental analysis and electrochemical analysis. Molecular structures of compounds L, L2Ag]NO3 and L2Ag]ClO4 were determined by single crystal X-ray diffraction analysis. It was found that the C=N double bond of the ligand rotated during the course of ligand coordination in the case of the perchlorate salt but not in the case of the nitrate salt. |
