Synthesis, structure, and facile oxidation of a novel 1,1′-bis(N,N-dimethylaminomethyl)ferrocene bridged diplatinum complex

The reaction of cis-PtCl2(dmso)2(dmso = dimethylsulphoxide) with the ferrocenyl amine (η5-Me2NCH2C5H4)2Fe yields the readily oxidised, cyclometallated derivative [η5-PtCl(dmso)Me2NCH2C5H3]2Fe through the intermediary of the complex [η5-trans-PtCl2(dmso)Me2NCH2C5H4]2Fe; an X-ray study of the cyclometallated species shows that the ferrocenyl bridged Pt atoms are located one above the other at a separation of 4.285(5)A.
