Abstract: The reaction beetwen tantalum pentakis(3,5-dimethyl-pyrazolate) and CS₂ afforded novel complex [Ta(=S)(dmpz)₂{(dmpz)₃CS}]. In this reaction the molecule of CS₂ undergoes scission with the migration of one sulfide to the tantalum atom while three pyrazolate residues migrate to carbon with the formation of unusual (dmpz)₃CS^– ligand. The structure of the product was established by X-ray diffraction.

Keywords: tantalum complexes, amides, pyrazolates, sulfides, carbon disulfide, dithiocarbamates.
