摘要： 合成了一类新的金属配合物[Cu(sampn)CuL](sampn4-:N,N′-1,2-丙二水杨酰胺根离子;L:2,2-联吡啶或1,10-菲绕啉),经元素分析、IR、电子光谱等手段推定配合物具有酚氧桥结构,Cu(Ⅱ)离子的配位环境为畸变四方构型。测定了配合物的变温磁化率,其数值用最小二乘法与修正的Bleaney-Bowers方程拟合,从中得到较大的θ值,表明双核分子间有较大的分子间相互作用。

Abstract: New metal complexes of [Cu(sampn)CuL] type were synthesized, where sampn4- denotes N,N'-1,2-propanedisalicylamidate anion and Ldenotes 2,2'-bipyridyl(bpy) or 1,10-phenanthroline(phen). Based on IR, elemental analyses and electronic spectra, the complexes are proposed to have phenoxy-bridged structure and to consist of the Cu(Ⅱ) in distorted planar environment. The complexes have been characterized with variable-temperature magnetic susceptibility (77～300K)and the observed data were fit to those from a modified Bleaney-Bowers equation by means of least-squares, resulting in a larger θ. This suggests that two binuclear units have a considerable intermolecular interaction.
