| Abstract | ||
| Two serious of rhenium (V) compounds were prepared: The first in trans- dioxo core with general formula:- trans- [(O)2 Re (Ln)2]X Where n=2=OPD= orthophenylene diamine n=3=HD= hexamethylene diamine These complexes were formed in high yield from reaction of [ReOX3(pph3)2] were X= Cl and Br as a starting materials in Acetone once and another in ethanol. The second compounds is cis-dioxo core with formula cis- [Re(O)2(m-tolunirile) bipy] Cl was prepare by heating [ ReO2 bipy Cl] as a starting materials in toluene as a solvent. All reactions were carried out under nitrogen Atmosphere. The properties and structure of these complexes are discussed. Also the stability of these complexes have been examined towards – irradiation. The structure of these complexes were confirmed by (C.H.N), I.R, (UV-Vis) spectra, electric conductivity measurements, along with HPLC technique to determine retention time (tR) and find out the purity of complexes and the number of isomers in solution, these complexes displayed single species, which confirmed the purity of complexes and the presence of one isomer in solution. This study show that all rhenium complexes have an octahedral structure. The proposed structures for these complexes are shown below | ||
