  • Thermal properties of volatile ruthenium(III) complexes
    Journal of Thermal Analysis and Calorimetry, 2012
    Co-Authors: Kseniya V. Zherikova, Ludmila N. Zelenina, Natalia B. Morozova, Tamara P. Chusova
    Abstract:

    Complexes of ruthenium(III) with the following Beta-Diketone derivatives: 2,4-pentanedione (Ru(acac)_3), 1,1,1,6,6,6-hexafluoro-2,4-pentanedione (Ru(hfac)_3), and 2-methoxy-2,6-dimethyl-3,5-heptanedione (Ru(mdhd)_3) were synthesized, purified, and identified by chemical analysis and melting points. By difference-scanning calorimetry (DSC) in vacuum the thermodynamic characteristics of melting processes were defined. Using the static method with quartz membrane zero-manometer, the temperature dependencies of saturated and unsaturated vapor pressure were obtained for Ru(hfac)_3. The standard thermodynamic characteristics of vaporization processes enthalpy ∆ H _ T* and entropy ∆ S° _ T* were determined.

  • Synthesis, spectral, and thermal characterizations of Ni(II) and Cu(II) Beta-Diketone complexes with thenoyltrifluoroacetone ligand.
    Spectrochimica acta. Part A Molecular and biomolecular spectroscopy, 2006
    Co-Authors: Zhimin Chen, Yiqun Wu, Fuxin Huang, Donghong Gu
    Abstract:

    Two kinds of nickel(II) and copper(II) Beta-Diketone complexes derived from thenoyltrifluoroacetone ligand with blue-violet light absorption were synthesized by reacting free ligand and different metal(II) ions in sodium methoxide solution. Their structures were postulated based on elemental analysis, ESI-MS, FT-IR spectra and UV-vis electronic absorption spectra. Smooth films on K9 glass substrates were prepared using the spin-coating method. Their solubility in organic solvents, absorption properties of thin film and thermal stability of these complexes were evaluated.
