  Synthesis, Spectral, Magnetic, Thermal and Antibacterial Properties of Metal Complexes of Isothipendyl

  摘要：

  New complexes of Mn(II), Cr(III), UO2(VI), Zn(II) and Cd(II) with isothipendyl hydrochloride (IPH.HCl) were prepared and their structures were determined by elemental analyses, IR, H-1 NMR and reflectance spectra as well as magnetic susceptibility and conductivity measurements. The spectral data suggest the bidentate nature of IPH in the complexes. An octahedral structure is proposed for the Mn(II), Cr(III) and UO2(VI) complexes, while a tetrahedral structure is suggested for the Zn(II) and Cd(II) complexes. Thermal studies (TGA/DTA) have been used to evaluate kinetic properties such as order of thermal reaction (n) and activation energy (Ea). The results of the antibacterial activity studies show that the complexes strongly inhibit Eschearichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella.

• Characterization of uranyl soaps by spectroscopic and thermal measurements
  作者：K. N. Mehrotra、Meera Sharma、A. S. Gahlaut

  DOI：10.1002/recl.19881070403

  日期：——

  The infrared and visible spectrophotometric data of uranyl soaps showed that metaloxygen bonds in uranyl soaps are not purely ionic but are partially covalent in character. The X-ray diffraction patterns confirmed the double-layer structure with molecular axes perpendicular to the basal plane. The thermal decomposition of these soaps was found to be kinetically of zero order and the energies of activation

  Lanthanum and cerium metals were prepared by electrolytic synthesis of amalgams in aqueous solutions followed by the thermal decomposition. The amalgamation yields were almost quantitative. The preparation yield of lanthanide metals, however, deteriorated during thermal decomposition due to a density difference between lanthanide and mercury. The gaseous impurities in the prepared metals were found
