  • Paramagnetic 18-Valence-Electron Alkylcyclopentadienylnickel(II) Bromide Dimers
    作者:Marion Schär、Dirk Saurenz、Frank Zimmer、Ina Schädlich、Gotthelf Wolmershäuser、Serhiy Demeshko、Franc Meyer、Helmut Sitzmann、Oliver M. Heigl、Frank H. Köhler

    The paramagnetic behavior of 18-electron cyclopentadienylnickel(II) complexes of the [CpNi(mu-Br)](2) type with two unpaired electrons per metal ion has been investigated by H-1 and C-13 NMR spectroscopy of [Cp'''Ni(mu-Br)](2) (1; Cp''' = 1,3,4-(Bu3C5H2)-Bu-t), [(CpNi)-Cp-3(mu-Br)](2) (2; Cp-3 = 1,3,4-iPr(3)C(5)H(2)), and [(CpNi)-Cp-4(mu-Br)](2) (3; Cp-4 = 2,3,4,5-iPr(4)C(5)H). The tri-tert-butylcyclopentadienyl derivative 1 crystallizes in the triclinic space group P (1) over bar and has been investigated by X-ray crystallography. Solid-state magnetic susceptibility measurements of 3 revealed an effective magnetic moment at room temperature of 4.04 mu(B),confirming the presence of two d(8) nickel(II) ions. While antiferromagnetic coupling via the bromo bridges is weak (J = 2.4 cm(-1)), zero-field splitting is substantial (D = +48.2 cm(-1)). NMR spectra of complexes 1-3 show signals with half-widths up to 3600 Hz within a spectral window exceeding 500 ppm (H-1) or 2200 ppm (C-13). An analysis of the spectra gave insight into the spin delocalization, the equilibrium orientation of the iPr substituents, and the presence of different conformers of compound 3. Paramagnetic behavior has also been observed for the Cp* derivative [Cp*Ni(mu-Br)](2) (Cp* = C5Me5) by H-1 NMR spectroscopy. The presence of two unpaired electrons is discussed in terms of the weak ligand field originating from the combined interaction of poorly pi accepting allcylcyclopentadienyl and pi donating bromo ligands with the nickel(II) center.
  • Bis(tetraisopropylcyclopentadienylnickel)dichalcogenides:  Complexes of the Novel [{CpME}<sub>2</sub>] Type (E = S, Se, Te)
    作者:Helmut Sitzmann、Dirk Saurenz、Gotthelf Wolmershäuser、Axel Klein、R. Boese
    DOI:10.1021/om000346i
    日期:2001.2.1
    The dinuclear dichalcogenides [(C5HR4)NiE}(2)] (R = CHMe2; E = S (2), Se (3), Te (4)) have been synthesized from [(C5HR4)NiBT}(2)] (1) (R = CHMe2) and the corresponding disodium dichalcogenides. Crystal structure analyses show four-membered Ni2E2 rings with weak, but significant E . . .E interaction. 1-4 were characterized electrochemically and reveal nickel-centered oxidations, bridging ligand-centered reductions, and the formation of mixed-valent Ni(II)/Ni(III) species.
