Synthesis and Spectral Characterization Studies of New Trimethoprim-Diphenylphosphate Metal Complexes

Abdel-Nasser M. A. Alaghaz, Rabie S. Farag, Mohammed A. Elnawawy, Ahmed D. A. Ekawy

Eight mononuclear Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II), Pb (II) and La (III) complexes of DPTMEBPP ligand were synthesized and determined by different physical techniques. The molar ratio for all synthesized complexes is M DPTMEBPP = 11 which was established from the results of chemical analysis. All the eight metal complexes are reported using elemental analysis, molar conductance, magnetic susceptibility, IR, UVVis, thermal analysis and 1H-NMR, 13C NMR, mass, XRD spectral studies. The molar conductance measurements of all the complexes in DMSO solution correspond to nonelectrolytic nature. The crystal field splitting, Racah repulsion and nepheloauxetic parameters and determined from the electronic spectra of the complexes. The presence of co-ordinated water molecules were confirmed by thermal studies. All complexes were of the high-spin type and found to have six-coordinate octahedral geometry except the Cu (II), Zn (II) and Pb (II) complexes which were four coordinate, square planar geometry for Cu (II) complex while tetrahedral geometry for Zn (II) and Pb (II) complexes.
