合成了两个新的Ru(II)配合物[(eta(6)-对伞花烃)RuCl(L2)]Pf6(R2)和[(eta(6)-C6H6)RuCl(L2)]Pf6(R4)，并与(E)-N-((6-bromopyridin-2-yl)methylene)-4-(methylthio)aniline(L2)配位，通过元素分析、氢谱、碳谱和红外光谱进行了表征。X-射线单晶研究表明，配合物R2和R4分别与(ETA(6)-对伞花烃)Ru(N2Cl)和(ETA(6)-C6H6)Ru(N2Cl)形成配位环境。用热重(TG)和差示扫描量热法(DSC)研究了化合物R2和R4的热稳定性。这些络合物在空气中的热分解温度分别为280℃和260℃。通过电子吸收光谱、荧光光谱和氧化还原行为研究了它们与小牛胸腺DNA(CT-DNA)的相互作用。结果表明，络合物与CT-DNA以静电相互作用方式结合。以R2和R4为原料，通过焙烧法制备了纳米RuO2。此外，还研究了超声波对纳米RuO2性能的影响。用红外光谱和X射线衍射仪对纳米颗粒进行了表征。并用扫描电子显微镜(SEM)研究了纳米粒子的大小和形貌。
Two novel Ru(II) complexes [(eta(6)-p-cymene)RuCl(L2)]PF6 (R2) and [(eta(6)-C6H6)RuCl(L2)]PF6 (R4), with ligand (E)-N-((6-bromopyridin-2-yl)methylene)-4-(methylthio)aniline (L2), were synthesized and characterized by elemental analysis, H-1 NMR, C-13 NMR and IR spectroscopy. Based on X-ray crystallography studies, complexes R2 and R4 have coordination environments with formulated (eta(6)-p-cymene)Ru(N2Cl) and (eta(6)-C6H6)Ru(N2Cl), respectively. The thermal stabilities of compounds R2 and R4 were studied by thermal gravimetric (TG) and differential scanning calorimetry (DSC). Thermal decomposition of these complexes was at 280 degrees C and 260 degrees C under air atmosphere respectively. The interaction of these complexes with calf thymus DNA (CT-DNA) was explored through electronic absorption spectra, fluorescence and redox behavior studies. The results showed that the complexes bind to CT-DNA with electrostatic interactions. Nanoparticles of RuO2 were prepared by calcination of R2 and R4. Also the role of the ultrasound waves on the characteristics of the RuO2 nanoparticles was studied. The nanoparticles were characterized by IR spectroscopy and X-ray diffraction (XRD). Also size and morphology of nanoparticles were studied by scanning electron microscopy (SEM).
