  Quantum chemical calculations, experimental investigations and DNA studies on (E)-2-((3-hydroxynaphthalen-2-yl)methylene)-N-(pyridin-2-yl)hydrazinecarbothioamide and its Mn(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes

  摘要：

  This paper presents a combined experimental and computational study of novel Mn(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes of (E)-2-((3-hydroxynaphthalen-2-yl)methylene)-N-(pyridin-2-yl)hydrazinecarbothioamide (H2L). The complexes have been characterized by elemental analyses, spectral (IR. UV-Vis, H-1 NMR and C-13 NMR), magnetic and thermal studies. Theoretical calculations have been performed to obtain IR spectra for the ligand and its complexes using AM1, MM, Zindo/1 and PM3 methods. Satisfactory theoretical-experimental agreements were achieved by the MM method for the ligand and PM3 for the metal complexes. Additional information is obtained from bond length calculations for all compounds by two methods, AM1 and MM. It was observed that the M-S bond length is longer than that of M-N in the Cu(II), Cd(II) and Mn(II) complexes and the M-O bond length is shorter than that of M-N in the case of the Ni(II) complex, and the same is noticed in the Zn(II) complex which contains M-O, M-N and M-S bonds and their bond lengths have the order M-S > M-N > M-O. DOS calculations were carried out by the MM (ADF) method for the ligand and the Cu complex, from which we concluded that the thiol form of the ligand is more active than thione form and this explains why most of the complexation is in that form. Also, valuable information is obtained from the calculation of molecular parameters for all compounds carried out by previous methods of calculation (electronegativity of the coordination sites, net dipole moment of the metal complexes, values of heat of formation and binding energy), which proved that the complexes are more stable than the ligand. The IR spectra show that H2L is coordinated to the metal ions in a mono, bi or tridentate manner. Furthermore, the kinetic and thermodynamic parameters for the different decomposition steps were calculated using the Coats-Red-fern and Horowitz-Metzger methods. Finally, biochemical studies showed that complexes 3 and 4 have a powerful and complete degradation effect on DNA. (C) 2012 Elsevier Ltd. All rights reserved.

  摘要：

  摘要 本文介绍了 (E)-2-((3-hydroxynaphthalen- 2-基)亚甲基)-N-(吡啶-2-基)肼碳硫酰胺(H 2 L)。配体及其配合物已通过元素分析、光谱（IR、UV-vis、 1 H NMR 和 13 C NMR）、磁性和热研究进行表征。IR光谱显示H 2 L以单负双或三方式与金属离子配位。建议所有配合物的结构都是八面体，除了 Hg(II) 配合物是四面体。已使用 AM1、MM、Zindo/1、MM + 和 PM3 方法进行理论计算以获得配体及其配合物的红外光谱。配体的 MM 方法和其配合物的 PM3 方法实现了令人满意的理论 - 实验协议。通过 MM (ADF) 方法对配体 Hg 复合物进行 DOS 计算，我们从中得出结论，配体的硫醇形式比硫酮形式更具活性，这解释了大多数络合发生在该形式中。使用 PM3 方法计算金属配合物的 IR 振动是最接近实验数据的方法，它可以
