| 摘要: 在CH3OH-H2O介质中,通过Ln(phen)2Cl(Ln=La、Sm、Gd、Dy、Tm、Yb;Phen=1,10—二氮杂菲)与Me4NBH2(NC4H4)2反应,制得了化学式为Ln(Phen)4(BH2(NC4H4)2)的希土配合物。IR光谱,11BNMR谱和摩尔电导率的结果表明,在配合物中,B原子通过B-H-Ln键与Ln2+发生单齿配位作用。 |

| Abstract: The 1, 10-phenanthroline(phen) complexes of rare earth dihydrobis (1-pyrrolyl)borates have been synthesized via the reactions between Me4NBH2(NC4H4)2 and Ln(phen)2Cl3 in methanol-water medium. These complexes are characterized by elementary analysis, molar conductivity, IR,11B NMR and TG-DTA. They have the following formula Ln(phen)4-BH2(NC4H4)2)3(Ln= La, Sm, Gd, Dy, Tm, Yb; phen = phenanthroline). The ligand phen is bonded to the rare earth via the nitrogen atoms.The molar conductivity data indicate that these complexes are not typically ionic compounds in DMF and MeOH. IR and 11B NMR spectra show the coordination of boron atom with Ln3+ by B-H-Ln bond. After a long time exposure to air at room temperature, the color of these complexes becomes darken. Their thermal stability are described. |
