1,2-Dithiooxalatokomplexe von Rhenium(I) und Rhenium(V)

1,2-Dithiooxalato Complexes of Rhenium(I) and Rhenium(V) Cs₄[Re₂(CO)₆(dtox)₃] (dtox ? 1,2-dithiooxalate) is formed by the reaction of Re(CO)₅Br with Cs₂dtox. The dimeric complex ion contains one ligand in a transplanar conformation connecting the two Re atoms, each bearing one chelating dtox ligand. The structure of Cs[ReO (dtox)₂] has been determined from X-ray data. Re is pentacoordinated with one oxygen and four sulfur atoms, which form the basis of a tetragonal pyramid. Re is situated 0.752 Å above the basal plane. The i.r. spectra of both compounds have been assigned.
