In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Redox-active films formed by electrochemical reduction of solutions of C60 and platinum complexes, published in 2002-07-31, which mentions a compound: 15227-42-6, mainly applied to redox active film electrochem reduction solution fullerene platinum complex; pyridine chloro platinum complex ferrocene electroreduction redox active film, Quality Control of cis-Dichlorobis(pyridine)platinum(II).
Electroreduction of a toluene-acetonitrile (4:1 volume/volume) solution of C60 and cis-Pt(py)2Cl2 in the presence of 0.10M tetra(n-butyl)ammonium perchlorate as supporting electrolyte produces a black, redox active film that coats the electrode surface. This film retains its redox activity when transferred to an acetonitrile solution that contains only the supporting electrolyte, 0.10M tetra(n-butyl)ammonium perchlorate. The film was characterized by IR spectroscopy, laser desorption mass spectrometry, and XPS spectroscopy. The formation of this film is dependent on the platinum complex used as precursor and on the potential range used during film growth. No film growth is observed when Pt(bipy)Cl2, Pt(py)2I2, cis-Pt(PPh3)2Cl2 or trans-Pt(py)2Cl2 were used as precursors, but {Pt(μ-Cl)Cl(C2H4)}2 is a useful precursor which allows film growth at less neg. potentials. Chem. prepared C60Pt1 is also electrochem. active when precipitated on a platinum electrode. The formation of an electroactive film from the electroreduction of C70 and cis-Pt(py)2Cl2 is also reported.
The article 《Redox-active films formed by electrochemical reduction of solutions of C60 and platinum complexes》 also mentions many details about this compound(15227-42-6)Quality Control of cis-Dichlorobis(pyridine)platinum(II), you can pay attention to it, because details determine success or failure
