Abstract EN

The present work include preparation of some transition metal complexes Cu (II) with Schiff base ligands L1 (benzylideneamino)pyrimidin-2(1H)-one) L, L2(Z)-4-((2- hydroxybenzylidene) amino) pyrimidin-2 (1H)-one) L2 and L3 4,4'-((1E,1'E)-pentane-2,4-diylidenebis (azanylylidene)) bis (pyrimidin-2(1H)-one) (pdp).

The ligands were prepared from condensation reaction of the benzaldehyde, Salicyaldehyde and Acetylacetone with cytosine respectively.

These compounds were characterized by elemental analysis, molar conductivity; magnetic susceptibility measurements, NMR spectroscopy for ligand, electronic and infrared spectroscopy.

These complexes were classified into two classes: 1-[CuL1Cl2], [CuL2Cl2], [CuL3Cl2] 2-[Cu (L2) 2Cl2], [Cu (L2) 2Cl2], [Cu (L3) 2Cl2] Low conductance value showed that all the prepared complexes are non-electrolyte and the magnetic susceptibility measurements, electronic spectroscopy showed that all the prepared complexes of Type (1) have a square planar geometry for copper complexes, the complexes of Type (2) have an octahedral geometry.
