The picture shows two copper complexes with picolinic and dipicolinic acids containing single and zigzag ladder structural Cu(II) ion chains. Magnetic measurements, single crystal EPR, and computational calculations are used to unveil the magnetic dimensionality of both systems. Experimental and theoretical results confirmed that the structural chains in both compounds behave as magnetic chains despite copper ions are weakly coupled by isotropic exchange.

具有吡啶甲酸和二吡啶甲酸配体的交换偶联铜 (II) 配合物的线性和锯齿形梯形链的 EPR、磁性和计算表征

图片显示了两种含吡啶甲酸和二吡啶甲酸的铜配合物，含有单梯形和锯齿状结构的 Cu(II) 离子链。磁测量、单晶 EPR 和计算计算用于揭示两个系统的磁维数。实验和理论结果证实，尽管铜离子通过各向同性交换弱耦合，但两种化合物中的结构链都表现为磁链。
