result showed that Cu (II) ion is coordinated by two oxygen atoms from lmx ligand and two nitrogen atoms from bipym ligand in a slightly distorted square pyramidal arrangement. The X-ray structural analysis shows that the complex crystallizes in the monoclinic system with a = 15.031(3), b = 14.2647(13), c = 16.687(4) Å, and space group P21/n. Thermal analysis studies was used to determine the decomposition
第二代喹诺酮类莱莫沙星与 2,2'-联吡啶胺的 Cu(II) 络合物配制成 [Cu(lmx)(bipym)Cl](CH 3 OH)·3H 2 O (1) [lmx = lemofloxacin, bipym = 2 ,2'-联吡啶胺]已合成并利用 X 射线单晶衍射和光谱方法表征。[Cu(lmx)(bipym)Cl](CH 3 OH).3H 2 O的晶体结构已通过X射线衍射确定,结果表明Cu(II)离子与来自lmx配体的两个氧原子配位和来自 bipym 配体的两个氮原子,呈略微扭曲的方形金字塔排列。X射线结构分析表明配合物在单斜晶系中结晶,a = 15.031(3), b = 14.2647(13), c = 16.687(4) Å,空间群 P2 1 /n。热分析研究用于确定复合物的分解模式,还确认晶格水分子和作为最终产物的金属氧化物的存在。溶液中液氮温度 (LNT) 下的 X 波段电子顺磁共振
