本文合成了2个新型双核铜(Ⅱ)配合物,[Cu(samen)Cu(NO_2-phen)]·H_2O和[Cu(sampn)Cu(NO_2-phen)]·2H_2O,samen~(4-),sampn~(4-)和NO_2-phen分别表示N,N′-乙二水杨酰胺根阴离子,N,N′-1,2-丙二水杨酰胺根阴离子和5-硝基-1,10-菲绕啉。经元素分析,IR,电子光谱等手段推知该类配合物具有酚氧桥及其Cu(Ⅱ)离子的配位环境为畸变四方构型。测得配合物的变温磁化率(4—300K),其数值已用最小二乘法与修正的Bleaney-Bowers方程拟合,求得交换积分,J=—63.0cm~(-1)(samen)和—46.5cm~(-1)(sampn),表明标题配合物中有反铁磁性超交换作用。
In this paper, two new binuclear copper (Ⅱ) complexes [Cu (NO 2 -phen)] · H 2 O and [Cu (sampn) Cu (NO 2 -phen) , sampn ~ (4-) and NO 2 -phen denote N, N’-ethanedisalicylamide anion, N, N’-1,2-propanedisalicylamide anion and 5-nitro- 10-phenanthroline. Through the elemental analysis, IR, electron spectroscopy and other means to infer such complexes with phenolic oxygen bridge and its Cu (Ⅱ) ion coordination environment is distorted tetragonal configuration. The temperature-dependent magnetic susceptibility (4-300K) of the complex was measured and the values were fit to the modified Bleaney-Bowers equation using the least squares method and the exchange integrals were obtained, J = -63.0 cm -1 (samen) and -46.5 cm -1 (sampn), indicating that the title complex has antiferromagnetic meta-exchange.
