Some novel tetradentate Schiff base complexes VO(IV) and Cu(II) involving fluorinated heterocyclic β-diketones and polymethylene diamines of varying chain length

摘要: The present article describes the synthesis, spectral, coordination and thermal aspects of N,N′-polymethylene bis(1-phenyl-3-methyl-4-trifluoroacetylimino-2-pyrazoline-5-ol)oxovanadium(IV) or copper(II) Schiff base complexes with alkyl backbones ranging from two to four carbons have been characterized on basis elemental analysis, magnetic moments, molar conductivity measurements, spectra (FTIR, ESR, UV-Visible, MS), VPO studies. vapour pressure osmometry (VPO) mass spectral studies indicate that are monomeric. An ESR study all these VO(IV) Cu(II) consistent square pyramidal planar geometries metal ions, respectively. In addition, kinetics thermodynamic parameters for different decomposition steps studied employing Horowitz-Metzger Freemen-Carroll methods.
