Structure and Magnetic Properties of a Nitroxide Diruthenium(II,III) Complex, [Ru2(O2CCMe3)4(tempo)2][Ru2(O2CCMe3)4(H2O)2](BF4)2 (tempo = 2,2,6,6-Tetramethylpiperidine-1-oxyl)

Abstract

Abstract A nitroxide complex, [Ru2(O2CCMe3)4(tempo)2][Ru2(O2CCMe3)4(H2O)2](BF4)2 (tempo = 2,2,6,6-tetramethylpiperidine-1-oxyl) has been prepared and characterized by elemental analysis, X-ray crystal structure analysis, and variable temperature magnetic susceptibility and ESR spectrum measurements. A fairly large antiferromagnetic interaction (J = −130 cm−1) between the diruthenium core and the nitroxide radical has been observed.
