摘要：
The reaction of Ln(acac)(3)center dot 3H(2)O with NIT-PhOH radical yielded two new Ln-radical complexes [Ln(2)(acac)(4)(NIT-PhO)(2)] (Ln=Tb (1), Y (2); acac=acetylacetonato, NIT-PhOH=2-(2'-hydroxyphenyl)-4,4,5,5-tetramethylimidazo-line-1-oxyl-3-oxide). Two complexes are isostructural and have binuclear structure in which two lanthanide ions are bridged by two radical ligands through their phenoxo-O atoms. DC magnetic susceptibility studies indicated that there exists weak antiferromagnetic interaction in complex 2. CCDC: 1878666, 1; 1878665, 2.
