The first one-dimensional compounds where [Ln(hfac)(3)] (Ln = Gd, Tb, Dy) building blocks are bridged by a verdazyl-based radical, namely 3-imidazolyl-1,5-dimethyl-6-oxoverdazyl, were prepared and their structures elucidated; the magnetic properties were measured for all compounds and quantitatively fitted for Ln = Gd(III) using an alternate chain model leading to J(1) = -1.58 cm(-1) and to J(2) = -0.42 cm(-1).
首次制备了一维化合物，其中[Ln(hfac)₃]（Ln = Gd、Tb、Dy）结构单元由基于氮氧自由基的基团即3-咪唑基-1,5-二甲基-6-氧代氮氧自由基桥联，并对其结构进行了阐明；对所有化合物进行了磁性测量，并使用交替链模型对Ln = Gd(III)进行了定量拟合，得到J(1) = -1.58 cm⁻¹和J(2) = -0.42 cm⁻¹。
