Özet:

In the present work, firstly the novel mono oxime (1) and asymmetric dioxime ligand (LH2) (2) derived 4′-hydroxyvalerophenone as ketone were prepared under optimum conditions. Then, the bis-dioxime-based and boronic acid-capped groups containing Fe(II) and Co(II) complexes [(L)2M(X)2(BA)2] (3-6) (L= Dioxime, M = Fe(II) or Co(II), X= Cl2 or H2O and BA = Butyl boronic acid (BBA) or Ferrocene boronic acid (FBA)) were synthesized in a two-necked round-bottom reaction flask by direct contact of dioxime ligand (2), and different boronic acid with metal salts (FeCl2.4H2O or CoCl2) without special requirement of any additional chemical process. The prepared ligands and its Fe(II) and Co(II) complexes were characterized by means of NMR spectra, FT-IR spectra, UV-Vis spectra, LC-MS, melting point and magnetic susceptibility measurements as well as elemental analysis. The spectroscopic results demonstrated that the proposed Fe(II) and Co(II) complexes are a six-coordinated species and octahedral geometry. The infrared spectra (FT-IR) of the Fe(II) and Co(II) complexes indicated the characteristic peak at range 1208-1217 cm-1 cm corresponding υ(B-O) stretching.
