以N,N′-双(2-氨乙基)草酰胺合铜[Cu(oxen)]作为螯合剂,合成和表征了4个草酰胺桥联的异双核配合物[Cu(oxen)Mn(L)2](ClO4)2。oxen表示N,N′-双(2-氨乙基)草酰胺根阴离子;L分别为N,N,N′,N′-四甲基乙二胺(tmen)、1,3-丙二胺(tmd)、1,2-丙二胺(tme)和乙二胺(en)。测定了配合物[Cu(oxen)Mn(tmen)2](ClO4)2的变温磁化率(4~300K);其数值用最小二乘法和从自旋Hamiltonian算符(H=-2JS1·S2-DS2Z1)导出的磁方程拟合,求得交换积分J=-26.8cm-1,表明双核配合物中金属离子间存在反铁磁性超交换作用。实验还发现双核配合物的抑菌活性优于配体的抑菌活性。
Four oxalamide bridged heterodinuclear complexes [Cu (oxen) Mn (Cu (oxen))] were synthesized and characterized using Cu (oxen) L) 2] (ClO4) 2. oxen represents an N, N’-bis (2-aminoethyl) oxalate anion; L is N, N, N ’, N’-tetramethylethylenediamine (tmen) (Tmd), 1,2-propylene diamine (tme) and ethylene diamine (en). The temperature-dependent magnetic susceptibility (4 ~ 300K) of Cu (oxen) Mn (tmen) 2] (ClO4) 2 was determined by the least square method and the spin Hamiltonian operator (H = -2JS1.S2- DS2Z1) derivation of the magnetic equation fit, obtained exchange integral J = -26.8cm-1, indicating that there is anti-ferromagnetic metal ion in the binuclear complex of the exchange effect. The experiment also found that the antimicrobial activity of the binuclear complex is better than the antibacterial activity of the ligand.
