【摘要】 合成了含有Ｃｌ－桥联配体的两个新的双核配合物：Ｃｕ２（ａｍｐｙ）２Ｃｌ４·１／２Ｃ２Ｈ５ＯＨ（ａｍｐｙ＝α－氨基吡啶）和Ｃｕ２［Ｎ，Ｎ’ｂｉｓ（ａｍｐｙ）－ｂｚａｃ（Ｈ２Ｏ）］Ｃｌ４·Ｃ２Ｈ５ＯＨ（ｂｚａｃ＝苯甲酰丙酮）．通过元素分析、ＩＲ、ＥＳＲ和室温磁化率表征，测定了这两个配合物的变温磁化率（４～３００Ｋ），其数值用最小二乘法与从自旋Ｈａｍｉｌｔｏｎｉａｎ算符导出的磁化率理论曲线拟合很好；求得了交换积分，对于配合物Ｃｕ２（ａｍｐｙ）２Ｃｌ４·１／２Ｃ２Ｈ５ＯＨ，Ｊ＝－４．７６Ｃｍ－２；对于Ｃｕ２［Ｎ，Ｎ’ｂｉｓ（ａｍｐｙ）－ｂｚａｃ（Ｈ２Ｏ）］Ｃｌ４·Ｃ２Ｈ５ＯＨ，Ｊ＝－４．７２ｃｍ－２，表明两个配合物中Ｃｕ（Ⅱ）－Ｃｕ（Ⅱ）核间有反铁磁相互作用．更多还原

【Abstract】 Two new binuclear complexes containing bichloro-bridging were synthesizednamely Cu2 (ampy )2Cl4· 1/2C2H5OH (ampy = α-aminopyridine ), Cu2[N, N’bis (ampy )-bzac(H2O )] Cl4·C2H5OH (bzac=benzoylacetone ). The complexes have been chracterized byelemental analyses, IR, ESR, electronic spectra, susceptibility. The variable-temperature magneticsusceptibilities (4～ 300 K) of the two complexes were measured and the susceptibility equationwas derived from H=2JS1·S2. The exchange integals, J, were found to be -4. 76 cm-1 and-4. 72 cm-1 for the two binuclear complexes respectively. This indicates a weakantiferromegnetic spin exchange interaction between Cu (Ⅱ)-Cu (Ⅱ) of the two binuclearcomplexes.更多还原
