The reaction of the benzothiazole derivatives N-phenyl-N-(2-benzothiazole)thiourea (Hpbt), 1-(1,3-benzothiazol-2-yl)-3-benzoylthiourea (Hbbt), methylbenzothiazol-2-ylidenecarbamodithioate (Hmby) and N-(benzothiazol-2-yl)-S,S′-dimethyldithiocarboimine (Hbdc) with [Re(CO)5Cl] led to the isolation of the neutral complexes of the type [Re(HL)(L)(CO)3] (HL = Hpbt (1), Hmby (3)) and [ReCl(HL)(CO)3] (HL = Hbbt (2), Hbdc (4)). In these complexes the ligands L act as monoanionic bidentate N,S-donor chelates, and HL is coordinated in a monodentate manner via the neutral sulfur atom only. The formation of 1 and 3 is due to the ease of thione-thiol tautomerization of the ligands Hpbt and Hmby. The crystal structures of the complexes were determined by X-ray single crystal diffraction. In addition, infra-red, 1H NMR and electronic properties are also reported.
