Title: Magnetic exchange interaction in gadolinium(III) complex having aliphatic nitroxide radical TEMPO

Abstract

We synthesized a new compound, [Gd(hfac){sub 3}(MeOH)(TEMPO)] (TEMPO = 2,2,6,6-tetramethylpiperidin-1-oxyl; Hhfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dione) with the metal/radical ratio of 1/1. This compound has an advantage in the magnetic analysis, because the exchange coupling system is described with a unique coupling parameter J, when compared to the structure and magnetic properties of the previous TEMPO and related complexes. The X-ray crystal structure analysis of [Gd(hfac){sub 3}(MeOH)(TEMPO)] revealed the N-O and Gd-O(N) bond lengths are 1.299(9) and 2.307(5) Å, respectively, and the Gd-O-N angle is 149.4(5)°. The magnetic study clarified the Gd{sup 3+}-radical antiferromagnetic interaction of 2J/k{sub B} = −3.5(1) K.
