| Abstract | ||
| New transition metals complexes of anticipated analgesic activity were prepared by coordination of Co (II), Ni (II) and Cu (II) metals with the ligand L = 4- aminoantipyrine (4-AAP) in 1:2 and 1:3 molar ratio. The metal ions were bidentately bonded to the ligand in the complexes. Complexes have been synthesized by direct reaction in neutral medium to give complexes of the general formula [(ML2)Cl2. 2H2O] and [(ML3)Cl2]. The molecular formula of these complexes were proved by CHN analysis in addition to the IR and UV spectra. The molar conductivity measurements showed the octahedral geometry around the metal ion. The geometry (three dimensional structures) of complex (IV) at minimized energy was established by chem.3D Ultra; molecular modeling and analysis confirmed the suggested structure | ||
