Interplay of Magnetic Exchange Interactions and Ni-S-Ni Bond Angles in Polynuclear Nickel(II) Complexes

摘要

The ability of bridging thiophenolate groups to transmit magnetic exchangeinteractions between paramagnetic Ni(II) ions has been examined. For thispurpose, dinuclear and trinuclear Ni(II)-complexes were prepared and fullycharacterized by IR- and UV-vis spectroscopy, X-ray crystallography, staticmagnetization measurements and high-field electron spin resonance (HF-ESR). Wecompare structural and magnetic properties of the two Ni(II)-complexes anddiscuss the relationships between magnetic interactions and chemical bonding.
