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, H-1 NMR, C-13{H-1} 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.
