A new binuclear complex [Ag(ntb)](NO)·(CHOH)·(CHCN) based on a tripodal ligand ntb (ntb = tris(2-benzimidazolylmethyl)amine) has been synthesized and structurally characterized by X-ray single crystal diffractometry. In the structure of the complex each center Ag(I) ion is coordinated by two N atoms from two benzimidazole arm of one ntb ligand and one N atoms from one benzimidazole arm of the other in a trigonal coordinated geometry, resulting in the construction of a binuclear complex. The complex units are further linked into a 1-D chain by hydrogen bonds. The emission spectrum of the complex has been investigated and shows a red-shift of the emission peak compared to the ligand and the existence of ligand-to-metal charge transfer process (emission peak at 468.2 nm). Cyclic voltammogram of the complex indicates a pair of quasi-reversible redox couple, corresponding to the Ag/Ag electrochemical process. Graphical Abstract: In the structure of the complex each center Ag(I) ion is coordinated by two N atoms from two benzimidazole arm of one ntb ligand and one N atoms from one benzimidazole arm of the other in a trigonal coordinated geometry, resulting in the construction of a binuclear complex.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR] |
