摘要 Three isostructural lanthanide complexes,namely[Ln(L)_(3)·CH_(3) OH](Ln=Tb(1),Dy(2),Ho(3),HL=N-(pyridin-2-ylcarbamothioyl)benzamide),were successfully synthesized and characterized by IR,UV,elemental analysis,single-crystal X-ray diffraction and DNA-biding analysis.X-ray single-crystal diffractions show that the family of lanthanide complexes crystallizes in monoclinic C2/c space group.Each lanthanide atom is coordinated with three carbonyl-O atoms,three pyridyl-N atoms and three imine-N atoms from three distinct L^(-1) ligands,forming a distorted tricapped trigonal prism.The binding properties of complexes with ct-DNA were studied by simulating the physiological environment of human body.The results suggest that compounds could bind with ct-DNA through interaction under a spontaneous process.
