A Chain Complex of Ruthenium(II,III) Cation Dimer Linked by a Nitroxide Radical, [Ru2(O2CCMe3)4(NITPh)n(BF4)n (NITPh = 2-Phenyl-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxy-3-oxide)

A chain complex of ruthenium(II,III) cation dimer linked by the nitroxide radical, [Ru2(O2CCMe3)4(NITPh)]n(BF4)n (NITPh = 2-phenyl-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxy-3-oxide) has been prepared and characterized. The structure with the alternated alignment of S = 3/2 (Ru(II,III) core) and S = 1/2 (NITPh) has been confirmed by the X-ray crystal analysis. The magnetic moment decreases monotonously with decrease of temperature.
