【摘要】 以亚硝酸根为桥联配体,端接1,10 邻菲啉(1,10 phen),合成的配合物[Cu2(L)4(NO2)2](ClO4)2·2C2H5OH通过采用元素分析、摩尔电导、红外光谱以及电子光谱等手段,推测此配合物具有亚硝酸根桥联双核铜(II)结构。配合物的变温磁化率(4.9～299K),其数值用最小二乘法和从自旋Hamiltonian算符(H^=-2J(S^1·S^2),S1=S2=1/2)导出的磁方程拟合,求得交换积分为J=-0.38cm-1,结果表明双核配合物中金属离子间存在弱的反铁磁自旋交换作用。更多还原

【Abstract】 A novel copper（Ⅱ） binuclear chain complex has been obtained, namely [Cu₂（L）₄（NO₂）₂]（ClO₄）₂·2C₂H₅OH, where L represents 1, 10-phenanthroline （phen）. Meanwhile, the IR, electronic spectra and the temperature-dependent magnetic susceptibilities of the complex was analyzed in the range of 4.9-299 K. Experimental data of magnetic susceptibilities is successfully fit to theoretical value based on the spin Hamiltonian operator, （H）^=-2J（（S）^₁·（S）^₂）, S₁=S₂=1/2, giving the magnetic exchange parameters of J=-0.38 cm^-1. The results show a weak antiferromagnetic exchange interaction between Cu（Ⅱ） ions in the complex studied.更多还原
