【摘要】 合成出化学式为 { [Cu(tren) ]2 (μ2 -CO3) } (ClO4 ) 4·H2 O(tren为N_氨乙基_二乙烯三胺 )的配合物。该配合物经过元素分析、红外和紫外 -可见光谱等结构分析 ,研究结果表明Cu (Ⅱ )具有三角双锥的配位构型 ,并被碳酸根CO2 -3阴离子桥联形成三核Cu (Ⅱ )配合物。变温 (5～ 30 0K)磁化率被测定和拟合 ,计算结果表明标题配合物中Cu (Ⅱ )离子之间存在着弱的铁磁性相互作用。更多还原

【Abstract】 The complex with { 2(μ 2-CO 3)}(ClO 4) 4·H 2O (tren: N_tris(2_aminethyl)amine) formula was synthesized, and was structurally characterized with element analysis, IR and UV_vis spectra. The result shows that the coordination polyhedron of copper(Ⅱ) ion in titled complex the can be described as trigonal bipyramidal, which is bridged by a μ 3_carbonato to form a trinuclear copper(Ⅱ) complex. Susceptibility dependence of temperature from 5～300 K) was measured and fitted. The calculated result indicates that a weak ferromagnetic interaction among Cu(Ⅱ) ions exists in the titled complex.更多还原
