This paper included preparation of ligand azo new which is derivative from 4,5-di phenyl imidazole. It also included the preparation of metal complexes for ions of Co(II), Ni(II),Cu(II),Zn(II),Cd(II) which is derivative from the new ligand. The ligand and metal complexes has been synthesized by FTIR, UV-Vis,1HNMR and mass spectrum, as the complexes have been synthesized by magnetic susceptibility. As result has proven that the prepared complexes have magnetic determination which are compatible with the octahedral shapes and the results of molar conductivity for the complexes that there is no ionic property for the complexes and based on these results. Octahedral shape has been suggested for all prepared complexes.

New ligand were synthesized by two steps in fist steps were prepared chalcones compound from reaction of various carbonyl compounds (3-amino acetophenone with salicyldehyde the second steps were closure of the ring by reacting (chalcones compound (AS) with thiouria, then reaction mixture was reflux for (8h)to produce pyrimidine derivatives (AST) also prepared some complexes with Fe(II),Co(II),Ni(II),Cu(II), the ligand (AST) with its complexes were characterized by (FT-IR,Uv-Vis,HNMR,Mass)-spectra, elemental analysis, metting point, molar conductivity).

This work discuss methods of preparation a series of organic is at in ligands via imination process, diazotaion reaction , cyclization reaction in types of conditions to synthesis many ligands from is at ine derivatives like ( is at in-thiadiazole , is at in- triazole, is at in- azo , is at ine –anil). All present organicis at ine ligands were characterized by spectral identification with types of techniques (Uv.Vis , FT.IR ,H.NMR, C.NMR)– spectrophotometric.

This literature review concerned with antipyrine compound. Antipyrine compound is very important compound in many chemistry fields such as in coordination chemistry, analytical chemistry as a reagent which continuously identified for possible uses and applications in several fields beside to pharmacological, medical and industrial fields.

This survey provides information on (methods of synthesis, reactions , application in the medical and biological activities , its uses and its source as (whether natural or synthetic ). Chalcones are chemical compound or natural molecules have a broad spectrum of bio- activities , which are of great interest in many fields. The chemistry of chalcones appeared information about its preparation methods as a starting material in many reactions like cyclization reactions and medical application

A ligand which is derived from 4,5-diphenyl imidazole has been prepared, the co-ordination of this ligand with the metal ions of Co (II),Ni(II),Cu(II),Zn(II),Cd(II) under optimum circumstances of concentration and PH , the results have shown that the concentration of these complexes would be comply with Lambert- Beers law ,based on these results ,a mole ratio has been calculated for the complexes of the mentioned ligand ,so the ratio of (metal :ligand) has been found equal to (1:2) , as the ligand and its metal complexes has been distinguished using UV- Visible spectrum and IR spectrum , the H1 NMR has shown a harmonization with chemical formulas and the results of magnetic sensitivity of metal complexes ions has confirmed that geometric figure of octahedral.
