that the copper(II) ion has a distorted square-pyramidal geometry with the trigonality index of τ = 0.35 and two intermolecular hydrogen bonds, which result in the formation of two dimensional networks in the ab plane. On the other hand, Cu(dpmed)Br2 displayed a near square-pyramidal geometry with the value of τ = 0.06. In both compounds, the NNN Schiff base and one Br atom occupy the basal plane, whereas
两种新型溴化铜 (II) 与含吡啶的席夫碱配体 Cu(pmed)Br2 和 Cu(dpmed)Br2 配合物,其中 pmed = N'-((pyridin-2-yl)methylene)ethane-1,2-diamine ( pmed) 和 dpmed = N,Ndiethyl-N'-((pyridin-2-yl)methylene)ethane-1,2-diamine (dpmed) 合成并使用 X 射线单晶结构分析、光学和磁化率测量进行表征。Cu(pmed)Br2 的晶体结构分析表明,Cu(II) 离子具有扭曲的四方锥体几何结构,三角指数 τ = 0.35 和两个分子间氢键,导致在 ab 中形成二维网络。飞机。另一方面,Cu(dpmed)Br2 显示出接近正方锥体的几何形状,τ = 0.06。在这两种化合物中,NNN 席夫碱和一个溴原子占据基面,而第五个顶端位置被另一个 Br 原子占据,位于更大的
