lanthanoid Ln(III) complexes was investigated in Me2SO including n-Bu4N(acac) and n-Bu4N(dibm) as ligands (where acac is the acetylacetonate anion and dibm is the diisobutrylmethanate anion). Reversible one electron reduction waves corresponding to Ln(III) complexes→Ln(II) complexes were observed in the concentration range of 5–20 mM of the ligands, including 1 mM lanthanoid perchlorates and 0.1 M TEAP
镧系LN(III)络合物的电化学行为在我研究了2 SO包括Ñ -Bu 4 N(ACAC)和Ñ -Bu 4 N(dibm)作为配体(其中ACAC是乙酰丙酮化物阴离子和dibm是diisobutrylmethanate阴离子) 。在5–20 mM的配体浓度范围内观察到了对应于Ln(III)配合物→Ln(II)配合物的可逆的一个电子还原波,包括1 mM镧系高氯酸盐和0.1 M TEAP。在存在5 mM配体的情况下,在0.1 M TEAP中,镧系元素络合物的半波电势为sce -1.66至-2.61 V ,具体取决于镧系元素(III)离子。

Anhydrous trisacetylacetonate complexes of yttrium, gadolinium, terbium, dysprosium, holmium and erbium have been prepared. Melting points, heats of fusion and i.r., visible and u.v. spectra are reported for these compounds and compared with the properties of the corresponding trihydrates. Additional properties reported are the PMR spectrum of the yttrium compound and the fluorescence spectrum of the
Several previously unreported adducts of rareearthacetylacetonates have been prepared and characterized by chemical analyses (including Karl Fischer titrations for water), i.r. spectra, and X-ray powder diffraction patterns. These adducts include compounds with methanol, ethanol, propanol, butanol, dioxane, pyridine, 2- and 4- methylpyridine, 2,4- and 2,6-dimethylpyridine, acetone, benzene, and acetylacetoneimine
