The ability of bridging thiophenolate groups to transmit magnetic exchange interactions between paramagnetic Ni(II) ions has been examined. For this purpose, dinuclear and trinuclear Ni(II)-complexes were prepared and fully characterized by IR- and UV-vis spectroscopy, X-ray crystallography, static magnetization measurements and high-field electron spin resonance (HF-ESR). We compare structural and magnetic properties of the two Ni(II)-complexes and discuss the relationships between magnetic interactions and chemical bonding.
