| Popis: | In this study, a dinucleating spacer incorporating two 2-aminopyridine units has been used to prepare seven novel dinuclear compounds. These molecules were characterized by elemental analyses, conductivity measurements, magnetic susceptibility, FT-IR, FAB-Mass, electronic, 1H and 13C{1H}NMR spectral studies. The complex [{trans,mer-RuCl2(DMSO)3}2(μ-5,5'-methylenebis(2-aminopyridine))].2DMSO, 2 was also characterized through 1H-1H COSY NMR. There are mainly three different formulations; [{cis,fac-RuCl2(SO)3}2(μ-MBAP)].2SO; [{trans,mer-RuCl2(SO)3}2(μ-MBAP)].2SO and [{trans-RuCl4(SO)}2(μ-MBAP)]2- [X]2+; where SO = DMSO / TMSO; MBAP = 5,5'-methylenebis(2-aminopyridine) and [X]+ = [(DMSO)2H]+, Na+ or [(TMSO)H]+. The coordination was found through cyclic nitrogen of pyridine ring in octahedral environment for both metal centers. The chemical behivour of [{cis,fac-RuCl2(DMSO)3}2(μ-5,5'-methylenebis(2-aminopyridine))].2DMSO, 1 and 2 in aqueous solution with respect to time was observed by conductivity measurements and UV-vis spectrophotometer. All complexes were found to possess prominent antibacterial activity against Escherichia coli in comparison to Chloramphenicol and Gatifloxacin. |
