| Abstract | ||
| 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. | ||
