Ferromagnetic chain complex of ruthenium(II,III) pivalate with pyridyl nitronyl nitroxide

摘要

A chain complex of ruthenium(II,III) dimer with pyridyl nitronyl nitroxide, [Ru-2(O2CCMe3)(4)(p-pynit)](n)(BF4)(n) (p-pynit = 2-(4-pyridyl)-4,3,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxyl 3-oxide) has been prepared and charactarized by the X-ray crystal structure analysis. The magnetic susceptibility data show that a ferromagnetic interaction is operative between the ruthenium(II,III) dimers and pyridyl nitronyl nitroxides. [References: 14]
