A one-dimensional Cu(II) coordination polymer with encapsulated antiferromagnetically coupled binuclear Cu(II) has been synthesized by using 5-nitroisophthalic acid (5-N-IPA) and 4-aminopyridine (4-APY) [Cu2(5-N-IPA)2(4-APY)4] n (1). Electrical properties are examined by complex impedance (Z*), dielectric permittivity (ε*), and ac conductivity studies at different frequencies (10 kHz-5 MHz) and temperatures (253-333 K). The contribution of grain and grain boundary has been explained by a different theoretical model. The variable temperature magnetic susceptibility data for compound 1 were recorded between 300 and 2 K. The shape of the curve (χM T vs T) indicates dominant antiferromagnetic coupling, which results from the interaction between the copper(II) atoms.

一维Cu（II）配位聚合物中反铁磁耦合的双核Cu（II）的磁和介电性质的研究。

通过使用5-硝基间苯二甲酸（5-N-IPA）和4-氨基吡啶（4-APY）[Cu2（5-N），合成了具有包封的反铁磁耦合双核Cu（II）的一维Cu（II）配位聚合物-IPA）2（4-APY）4] n（1）。通过复阻抗（Z *），介电常数（ε*）和在不同频率（10 kHz-5 MHz）和温度（253-333 K）下的交流电导率研究来检查电性能。晶粒和晶界的贡献已通过不同的理论模型进行了解释。在300至2 K之间记录了化合物1的可变温度磁化率数据。曲线的形状（χM T与T）表示主要的反铁磁耦合，这是由铜（II）原子之间的相互作用引起的。
