Description in English The complexes [(mmb)Re(CO)(3)Cl], [(mtb,)Re(CO)(3)Cl], [(mmb)OsCl(Cym)](PF6) and [(Cym)OsCl(mtb)](PF6) where Cym = p-cymene, mmb = 1-methyl-(2-methylthiomethyl)-1H-benzimidazole and mtb = 1-methyl(2-tert-butylthiomethyl)-1H-benzimidazole were synthesized and, except for the latter, structurally characterized. In comparison with other late transition metal compounds of these N-S chelate ligands the rhenium(l) systems exhibit a balanced coordination to both N and S donor atoms. Anodic one-electron oxidation produces EPR-silent rhenium(II) states whereas the osmium(111) species [(mmb)OsCl(Cym)](2+) could be identified via EPR and UV/VlS spectroelectrochemistry. Workplace J.
