| Abstract: | Synthesis and characterization of seven ruthenium(II) and ruthenium(III) complexes of sulfoxide with 2-aminobenzothiazole are reported. Three different formulations exist: cis,cis,cis-RuCl2(SO)2(2-abtz)2] and trans,trans,trans-RuCl2(SO)2(2-abtz)2] and trans-RuCl4(SO)(2-abtz)] ? X]+ (where SO?=?dimethyl sulfoxide (dmso) or tetramethylenesulfoxide (tmso); 2-abtz?=?2-aminobenzothiazole and X]+?=?H(abtz)]+, Na+]. These complexes were characterized by elemental analyses, conductivity measurements, magnetic susceptibility, FTIR, 1H NMR, 13C{1H} NMR and electronic spectroscopy. Some of the complexes were screened for their antibacterial activity and are found to be potent against the gram negative bacteria Escherichia coli. |
