  Solution studies of lanthanide (III) complexes based on 1,1,1,5,5,5-hexafluoro-2,4-pentanedione and 1,10-phenanthroline Part-I: Synthesis, 1H NMR, 4f–4f absorption and photoluminescence

  摘要：

  Solution studies on the complexes of the type [Ln(hfaa)(3)(phen)(2)] (Ln = La, Pr and Nd) and [Ln(hfaa)(3)phen] (Ln = Nd, Ho, Er and Yb; hfaa stands for the anion of 1,1,1,5,5,5-hexafluoro-2,4-pentanedione and phen stands for 1,10-phenanthroline) are presented. These complexes are synthesized in high yields by an in situ method in which hfaa, ammonium hydroxide, lanthanide chlorides and phen were allowed to react in 3:3:1:1 molar ratio in ethanol. In the case of neodymium both eight- and ten-coordinate complexes are isolated. The paramagnetic shifts of the methine protons of beta-diketone have their sign opposed to those of paramagnetic shifts of phen protons and the shifts are dominated by dipolar interactions. The inter-and intramolecular shift ratios have been calculated and discussed. The 4f-4f absorption spectra of the complexes of Pr, Nd, Ho and Er are analyzed. The eight-and ten-coordinate neodymium complexes display distinctively different band shapes of the (4)G(5/2),(2)G(7/2) <- I-4(9/2) hypersensitive transition. The efficient energy transfer from ligand to Pr(III) is reflected by strong red luminescence of this complex at room temperature. (C) 2010 Elsevier B.V. All rights reserved.

  Abstract The coordination chemistry of Ln(hfpd)3 (hfpd=1,1,1,5,5,5-hexafluoropentane-2,4-dionate) with phen and bpy depends on the size of the Ln3+ ion and on the used solvent. The complexes [Er(hfpd)3(phen)] (7) and [Er(hfpd)3(bpy)] (14) were obtained from the synthesis of Er(CF3SO3)3 with Hhfpd, CsOH and either 1,10-phenanthroline or 2,2′-bipyridine in acetonitrile. The structure of 7 was determined

  摘要Ln（hfpd）3（hfpd = 1,1,1,5,5,5-六氟戊烷-2,4-二酸酯）与phen和bpy的配位化学取决于Ln3 +离子的大小和所用的溶剂。[Er（hfpd）3（phen）]（7）和[Er（hfpd）3（bpy）]（14）的配合物是由Er（CF3SO3）3与Hhfpd，CsOH和1,10-菲咯啉或2,2'-联吡啶在乙腈中。通过X射线晶体学确定7的结构。根据化学计量和光谱性质，类似的反应但与其他多种镧系元素在甲醇中进行，导致分离出五种不同类型的配合物。稍后在镧系元素中包含元素[Ln（hfpd）3（bpy）]（对于Ln = Dy，Ho和Yb）和[Ln（hfpd）3（phen）]（对于Ln = Tb） ，Ho和Yb），就像7一样，而对于早期的镧系元素，[Ln（hfpd）3（bpy）2]（对于Ln = La和Sm）和[Ln（hfpd）3（phen）2]（对于Ln = La，分离出C
