    Molecular structure and spectroscopic studies on novel complexes of coumarin-3-carboxylic acid with Ni(II), Co(II), Zn(II) and Mn(II) ions based on density functional theory
    摘要:
    Novel Ni(II), Co(II), Zn(II) and Mn(II) complexes of coumarin-3-carboxylic acid (HCCA) were studied at experimental and theoretical levels. The complexes were characterised by elemental analyses, FT-IR, H-1 NMR, C-13 NMR and UV-Vis spectroscopy and by magnetic susceptibility measurements. The binding modes of the ligand and the spin states of the metal complexes were established by means of molecular modelling of the complexes studied and calculation of their IR, NMR and absorption spectra at DFT(TDDFT)/B3LYP level. The experimental and calculated data verified high spin Ni(II), Co(II) and Mn(II) complexes and a bidentate binding through the carboxylic oxygen atoms (CCA2). The model calculations predicted pseudo octahedral trans-[M(CCA2)(2)(H2O)(2)] structures for the Zn(II), Ni(II) and Co(II) complexes and a binuclear [Mn-2(CCA2)(4)(H2O)(2)] structure. Experimental and calculated H-1, C-13 NMR, IR and UV-Vis data were used to distinguish the two possible bidentate binding modes (CCA1 and CCA2) as well as mononuclear and binuclear structures of the metal complexes.

    complexation of coumarin-3-carboxilic acid (HCCA) with Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) at 37 °C and in 0.16 M NaClO4 is discussed. Speciation profiles obtained by potentiometric titrations show that in aqueous solution a complexation occurs at a ligand-to-Cr(III), -Ni(II) and -Cu(II) ratio of 1:1, and at a ligand-to-Co(II) and -Zn(II) ratio of 1:1, 2:1 and 3:1. For Co(II)-HCCA system also a polynuclear
    本文讨论了香豆素-3-羧酸 (HCCA) 在 37 °C 和 0.16 M NaClO 4 中与 Cr(III)、Co(II)、Ni(II)、Cu(II) 和 Zn(II) 的络合。通过电位滴定获得的形态分布表明,在溶液中,配体与 Cr(III)、-Ni(II) 和 -Cu(II) 的比例为 1:1,配体与 Co(II) 和 -Zn(II) 的比例为 1:1、2:1 和 3:1。对于 Co(II)-HCCA 系统,也形成了多核物质(即 Co2(OH)(CCA)2+)。借助 UV-Vis、IR 和 X 射线衍射确定 HCCA 对不同属离子的配位点。HCCA 的固态化学富含属阳离子的两种新的 X 射线分辨结构,这些结构也得到了报道和讨论。从晶体堆积分析结果中可以看出弱相互作用的复杂基序,这导致了超分子有趣的排列,这在以前的文献中尚未披露和争论关于香豆素-3-羧酸同构配位化合物。
