摘要：

A chain complex of diruthenium(II,III) cation dimer linked by a nitroxide radical, [Ru-2(O2CCMe3)(4)(nitph)](n)(BF4)(n) (nitph = 2-phenyl-1,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1-oxyl-3-N-oxide), has been prepared and characterized. The structure with an alternating alignment of Ru(II,III) core and nitph has been confirmed by the X-ray crystal analysis. The magnetic moment decreased steadily with decrease of temperature, against the expectation of ferrimagnetic behavior based on the alternated alignment of S-1 = 3/2 (for Ru(II,III) core) and S-2 = 1/2 (for nitph). It has been found that the zero-field splitting plays an important role in the magnetic behavior in addition to the interaction between the Ru(II,III) core and nitph.
