    Notes: Summary.  The syntheses, properties, and chemical shifts of the heterometal gold(I) complexes FcNAuċP(C6H4Cl-4)3 (1), FcN′[AuċPPh3]2 (2), and Fc′[AuċPPh3]2 (3) are reported. The electrochemical behaviour of complexes 1 and 3 is compared with that of the related platinum derivatives (FcN)2Pt (4) and FcNPtClċPPh3 (5). Cyclovoltammetric measurements confirm reversible one-electron transfers..

    Notes: Compared to parent ferrocene, the redox potential of the FeII/FeIII transition is shifted to much more cathodic values in B-N adducts 1·Do and 2·(Do)2 of borylated ferrocenes FcBMe2 (1) and 1,1′-fc(BMe2)2 (2) with pyridine bases Do [Fc: (C5H5)Fe(C5H4); fc: (C5H4)Fe(C5H4); Do: γ-picoline, 4-(dimethylamino)pyridine, N-(n-propyl)-4-(4′-pyridyl)pyridinium hexafluorophosphate]. Electron donation by one single BMe2·Do substituent at the cyclopentadienyl ligand is approximately equal to the positive inductive effect of the five methyl groups in a C5Me5 (cp*) moiety. Using the bidentate nitrogen ligand 4,4′-bipyridine (bipy), the dark-purple dimetallic complex 1·bipy·1 is obtained upon reaction with 2 equiv. of 1. 1·bipy·1 has been structurally characterized by X-ray crystallography. The compound tolerates loss of two electrons at the ferrocene groups, as well as two one-electron reductions at the bipy linker. Dark purple coloured coordination polymers [2·bipy]n are accessible from bipy and 1 equiv. of the diborylated derivative 2. The intense colours of 1·bipy·1 and [2·bipy]n are indicative of charge-transfer interactions between the electron-rich ferrocene fragments and the viologen-like R3B-bipy-BR3 acceptor. Neat, solid [2·bipy]n is thermally stable up to 240 °C, but in the presence of toluene, polymerization is fully reversible at about 85 °C.

    1,1′-Bis(stannyl)- and 1,1′-Bis(chlorostannyl)ferrocenes Studied by Multinuclear Magnetic Resonance, Temperature-Dependent 57Fe- and 119Sn-Mössbauer Spectroscopy, and Electrochemistry (1999)

    Notes: The 1,1′-bis(chlorostannyl)-substituted ferrocenes Fe(C5H4-SnMe2Cl)2 (2), Fe(C5H4-SnMeCl2)2 (3) and Fe(C5H4-SnCl3)2 (4) were prepared, starting from 1,1′-bis(trimethylstannyl)ferrocene (1). Treatment of the chlorides with Li[AlH4] afforded the 1,1′-bis(hydridostannyl)-subsituted ferrocenes Fe(C5H4-SnMe2H)2 (5), Fe(C5H4-SnMeH2)2 (6) and Fe(C5H4-SnH3)2 (7), respectively. All complexes 1-7 were studied by 1H-, 13C-, and 119Sn-NMR spectroscopy with 1D and 2D techniques. The compounds 1-4 were investigated by temperature-dependent 119Sn- and 57Fe-Mössbauer spectroscopy. The electrochemistry of 1-5 gave evidence of reversible one-electron oxidation processes. The molecular structure of 1,1′-bis(trichlorostannyl)ferrocene (4) was determined by X-ray structural analysis, and there was no indication of intra- or intermolecular Sn···Cl···Sn interactions. This direct structural information proved to be consistent with both the Mössbauer and the solution NMR spectroscopic data.
