Preparation , Characterization, and Theoretical Treatment Complexes Of Some Transition Metals with N5 Acyclic Derived From 2,6-diacetyl pyridine

Abstract

   A series  of  transition  metal  complexes with [2,6-diacetimino-pheylenediamine –[2,2^,diyl] pyridine ]of the general  formula [MLCl]Cl , M= Co(II), Ni(II) and Cu(II) , respectively  have been  synthesized  and  fully characterized  on the bases  of C.H.N.M  elemental analysis, ¹HNMR , UV- Visible and FTIR spectra , in addition the structure of complexes was characterized by  magnetic moments and molar conductance in DMSO solution ,and molar ratio of metal  were also determined. From the above of these studies and measurements suggest an octahedral geometry around Co(II) , Ni(II) and Cu(II) .

A theoretical treatment of the formation of complexes in the gas phase was studied, this was done using the HYPERCHEM-6 program for the Molecular mechanics and Semi-empirical calculations.
