N，N′－双（2－氨乙基）草酰胺合铜（Ⅱ）的铜（Ⅱ）－锰（Ⅱ）配合物的合成和磁性

Synthesis and Magnetism of Copper(Ⅱ)- Manganese(Ⅱ)Complex of N,N'- Bis(2-aminoethyl)Oxamidocoppcr(Ⅱ)

合成和表征了新型异双核配合物（ｃｕ（ｏｘａｅ）ＭｎＬ２］（ｃｌｏ４）２，ｏｘａｅ表示Ｎ，Ｎ′－双（２－氨乙基）草酰胺根阴离子，Ｌ表示５－硝基－１，１０－邻菲罗啉（ＮＯ＿２·ｐｈｅｎ）。测定了配合物的变温磁化率（４．２～３００Ｋ），并用最小二乘法和从自旋Ｈａｍｉｌｔｏｎｉａｎ算符，导出的磁方程拟合，求得交换积分Ｊ＝一３５．７８ｃｍ一１，表明Ｃｕ（Ⅱ）－Ｍｎ（Ⅱ）双核配合物具有反铁磁超交换作用。

A novel heterobinuclear complex, namely O(Cu(Oxae)MnL2)(ClO4)2,is synthesized and characterized,where oxae denotes N,N' -bis(2一aminoethyl) Oxamido dianion and L denotes 5-nitro-1,10- phenanthroline(NO2.phen).Variable-temperature magnetic susceptibility of the complex is measured over the 4.2-300K range and the data are least- squares fit to a susceptibility equation derived from spin Hamiltonian H=一2JS。The exchange integral,J,is found to be equal to -35.78 cm-1,indicating an antiferromagnetic superexchange interaction between the metal lons。
