Synthesis and properties of lanthanide complexes with tetrapyrazinoporphyrazine and its substituted derivatives
摘要:
Reactions of dicyanopyrazine and its tert-butyl-, diphenyl-, and dipyridyl-substituted derivatives with erbium, thulium, ytterbium, and lutetium chlorides, acetates, and acetylacetonates gave the corresponding tetrapyrazinoporphyrazine metal complexes which were characterized by elemental analyses, and IR, H-1 NMR, and electronic absorption spectra. The stability of the complexes to thermooxidative decomposition in air was also studied.

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。

The synergistic effect by sublimation manifests itself in an increase in the volatility of nonvolatile or slightly volatile compounds in the presence of highly volatile agents. In this study, manifestations of the synergistic effect are demonstrated by the evaporation of mixed ligand complexes, derivatives of lanthanide acetylacetonates and neutral organic ligands, and by evaporation of the following mixtures: yttrium and zirconium acetylacetonates, lanthanum and nickel dipivaloylmethanates and acetylacetonates, and lanthanum and aluminum acetylacetonates.

Lanthanide complexes of acetylacetonate and 5,10,15,20-tetra [para-(4-fluorobenzoyloxy)-meta-methoxy]phenylporphyrin having the general formula Ln[(FBOMP)(4)P](acac) (where Ln=Er, Tm, Yb; FBOMP=[para-(4-fluorobenzoyloxy)meta-methoxy]phenyl; acac=acetylacetone; P=porphyrin) have been prepared and characterized. A structure is proposed in which one 5,10,15,20-tetra[para-(4-fluorobenzoyloxy)meta-methoxy]porphyrin molecule is coordinated to a rare earth ion in a tetradentate fashion, while one acetylacetonate molecule is coordinated to the same metal ion in a bidentate fashion.
