2-diylbis(azanediyl)]bis[(4-chlorophenyl)methylene]diphosphonic acid (L1P), [ethane-1, 2-diylbis(azanediyl)]bis[(4-bromophenyl)methylene]diphosphonic acid (L2P), and their corresponding copper complexes, Cu2(L1P)2 (1) and Cu2(L2P)2 (2) are described herein. Complex 2 was structurally characterized with X-ray single crystal diffraction. The structure of 2 consists of five-coordinatecopper(II) ions with a distorted
合成两种新的二膦酸配体[乙烷-1,2-二基双(氮杂二烷基)]双[(4-氯苯基)亚甲基]二膦酸(L1P),[乙烷-1,2-二基双(氮杂二烷基)]双[ (4-溴苯基)亚甲基]二膦酸(L2P)及其相应的铜配合物Cu2(L1P)2(1)和Cu2(L2P)2(2)在本文中进行了描述。配合物 2 用 X 射线单晶衍射进行了结构表征。2 的结构由五配位铜 (II) 离子组成,具有扭曲的方形金字塔排列,由来自膦酸酯基团的 OPO 双重桥接。Cu-Cu 距离为 4.7810(2) A。晶体堆积由核间氢键决定,导致一维链。热重研究 (TG-DTA)、UV/Vis 漫反射、红外和 (1H 和 13C) NMR 光谱的结果,
