A new tris(ferrocenylamine) ditertiary phosphine: Synthesis and co-ordination studies

The new tris(ferrocenylamine) ditertiary phosphine 1,1′-{FcCH2N(CH2PPh2)CH2(η5-C5H4)}2Fe [Fc = (η5-C5H5)Fe(η5-C5H4)] has been prepared along with two coordination complexes. All compounds have been characterised by a combination of spectroscopic and analytical methods. The single crystal X-ray structure of the pentametallic Ru2Fe3 complex 5 has been determined.

The new ferrocenyl functionalised ditertiary phosphine 3 and two complexes of AuI and RuII were prepared and studied by multinuclear NMR spectroscopy, single crystal X-ray diffraction and cyclic voltammetry. The single crystal X-ray structure of 5 represents an unusual example of a pentametallic Ru2Fe3 complex.Figure optionsDownload as PowerPoint slide
