Bis[2-(dimethylaminomethyl)ferrocenyl]-thalliumchlorid — ein heterobimetallischer Chelatkomplex
摘要:
Tris[2-(dimethylaminomethyl)ferrocenyl]-thallium (FcN)(3)Tl (I) reacts with the vanadium(IV)/(V) chlorides VCl4(THF)(2), Cp(2)VCl(2), CpVOCl(2), VOCl3 with substitution of, in each case, a chlorine atom by an FcN-ligand to form bis[2-(dimethylaminomethyl)ferrocenyl]thallium chloride (FcN)(2)TICl (II) and thermally unstable (not isolable) FcN-derivatives of four/five-valent vanadium. A detailed characterization of II has been carried out by IR, mass, H-1 NMR, UV-vis and Mossbauer spectroscopies. X-ray crystal structure analysis and low temperature H-1 NMR spectroscopy prove the chelate-structure of II.
