the complexes were characterized by elemental analysis (EA), EDTA complexometric titration, infrared spectroscopy (FTIR) and X-ray powder diffraction (XRD). By these results, the minimum formula was established as [M(Nor)2(H2O)2]·nH2O, where n = 3 (Ni), 2.5 (Mn Co, Zn), or 2 (Cu). The evolved gases identified during thermal decomposition of Ni and Cu complexes were ethylene, CO2 and CO for Ni; CO2
过渡金属与诺氟沙星(Nor)的配位化合物具有提高其效力的潜力,正如文献中某些化合物所讨论的那样。通过用诺氟沙星钠盐溶液沉淀相应的金属阳离子(M = Mn(II),Co(II),Ni(II),Cu(II)和Zn(II))来制备固态复合物。使用热重分析和差热分析(TG / DTG–DTA)和逸出气体分析(EGA / TG-FTIR)研究了在氧化和热解条件下的热行为,并通过元素分析(EA),EDTA络合滴定法对络合物进行了表征。 ,红外光谱(FTIR)和X射线粉末衍射(XRD)。根据这些结果,最小公式确定为[M(Nor)2(H 2 O)2 ]· n H 2 O,其中n = 3(Ni),2.5(Mn Co,Zn)或2(Cu)。Ni和Cu配合物热分解过程中发现的逸出气体为乙烯,CO 2和Ni的CO。CO 2和乙烷用于铜。另外,使用琼脂扩散法通过体外药敏试验评价复合物的抗菌活性,并将结果与未
