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。
The novel heterodinuclear complex (cu (oxae) MnL2] (clo4) 2 was synthesized and characterized. Oxae represents N, N’-bis (2-aminoethyl) oxalate anion, L represents 5-nitro- 10-phenanthroline (NO 2 · phen) .The magnetic susceptibility (4.2-300 K) of the complex was measured and fitted by the least-square method and the magnetic equation derived from the spin Hamiltonian operator to obtain the exchange The integral J = 35.78cm-1, indicating that Cu (Ⅱ) -Mn (Ⅱ) binuclear complex has antiferromagnetic super-exchange.
