    Thermal and Antibacterial Studies of Novel Lanthanide–Schiff Base Complexes
    摘要:
    Novel lanthanide complexes with the general formula [Ln(L)(ONO2)(H2O)(2)] have been synthesized and characterized. {L = 5-bromosalicylidene 4-amino 3-mercapto-1,2,4-triazine-5-one (BrSAMT), Ln = La(III), Ce(III), (Pr(III) Eu(III), Sm(III), Nd(III), Tb(III), Dy(III), and Y(III)}. The thermal, magnetic, molar conductance, and spectral studies confirm that the ligand coordinates through sulfur, azomethine nitrogen, and phenolic oxygen. A scheme of thermal decomposition of the complexes is also proposed. La, Eu, and Yb complexes of BrSAMT show antibacterial activity against gram negative bacteria such as E. coli, Pseudomonas aeruginosa, Salmonella typhi, and Shigella flexneri.

  • Thermal decomposition of formates. Part IX. Thermal decomposition of rare earth formate anhydrides
    作者:Yoshio Masuda
    DOI:10.1016/0040-6031(83)80108-7
    日期:1983.9
    Abstract The thermal decomposition of rare earth formate anhydrides in a flowing nitrogen atmosphere was studied systematically by means of thermogravimetry and differential thermal analysis. The decomposition consisted of two or three stages 2 Ln(HCO 2 ) 3 → 2 LnO(HCO 2 ) → Ln 2 O 2 ·CO 3 → Ln 2 O 3 The monoxyformate did not appear in the decomposition of the lighter element formates except for lanthanum
    摘要 采用热重法和差热分析法,系统地研究了稀土甲酸酐在流动氮气气氛中的热分解。分解由两个或三个阶段组成 2 Ln(HCO 2 ) 3 → 2 LnO(HCO 2 ) → Ln 2 O 2 ·CO 3 → Ln 2 O 3镧甲酸。在整个系列中都观察到了碳酸氢盐。镨和钕的碳氧酸盐晶体结构为单斜晶型,其他元素为四方晶型。稀土甲酸盐的热稳定性与其结构畸变有关,这必须归因于稀土金属离子半径的收缩。镧分解为甲酸镝的第一阶段是 Avrami 型反应。钬到镥的甲酸盐在分解的主要第一阶段熔化,它们的动力学是一级反应的特征。确定了分解主要阶段的动力学参数,如活化能和指前因子。

    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。

    parameter consideration it is concluded that these compounds are the rare earth monoxides. For Ln =Gd, Dy, Tm, no reaction is observed at 50 kbar and 1000°C. The rare earth monoxides show a variety of properties: LaO, CeO, PrO, and NdO are metallic with the rare earth in the trivalent state; EuO and YbO are semiconductors with the rare earth in the divalent state; SmO is metallic with samarium in an intermediate

    作者:B. Sundaravel、C. M. Babu、B. Palanisamy、M. Palanichamy、K. Shanthi、V Murugesan

    PrAlPO-5 with (Al+P)/Pr ratios of 25, 50, 75 and 100 molecular sieves were successfully synthesized by hydrothermal method. These molecular sieves were characterised using XPS, TPD-NH3, ex-situ pyridine adsorbed IR, TPR, TGA, 27Al and 31P MAS-NMR and ESR studies. The incorporation of praseodymium in the framework of AlPO-5 was confirmed by XRD, DRS UV-vis and 27Al and 31P MAS-NMR analysis. ESR spectrum showed the presence of adsorbed oxygen. The nature and strength of acid sites were identified by ex-situ pyridine adsorbed IR and TPD-NH3. The BET surface area was found to be in the range of 238−272 m2 g−1. The catalytic activity of the molecular sieves was tested for the liquid phase aerobic oxidation of ethylbenzene. Acetophenone was found to be the major product with more than 90% ethylbenzene conversion. ICP-OES analysis revealed the presence of praseodymium intact in the framework of AlPO-5 up to five cycles.

    The proton relaxivities of the Gd3+ complex decrease with the increase of pH, and at pH > 6, the low relaxivity values indicate the probable absence of H2O in the inner sphere and the predominance of the eight-coordinated dimer species [Gd2(L-O)2].4- The results of ESI-TOF MS studies of the complexes of La3+, Nd3+, and Lu3+ proved the formation of dinuclear dimers in dilute (0.25 mM) solutions. pH-potentiometric
