    • Abstract

       

      Complexes of Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Pd(II) with di-N-phenyl pyromellitic diimide (PhPMDI) and di-N-pyridyl pyromellitic diimide (PyPMDI) were prepared and characterized based on analytical, molar conductance, magnetic, IR, PMR, electronic and ESR data. Based on analytical and molar conductance, the complexes have been formulated as [M(PhPMDA)(H2O)2]n (M = Mn, Fe, Co, Ni), [Cu(PhPMDA)]n [Pd2(PhPMDA)Cl2(H2O)2], [M(PyPMDA)]n (M = Mn, Fe, Co, Ni and Cu) and [Pd2(PyPMDA)Cl2] In all these complexes PhPMDA acts as a mononegative bidentate ligand whereas PyPMDA acts as a mononegative tridentate one in the form of amide rather than imide. The geometries of the complexes have been proposed based on the electronic spectra. The various bonding parameters have been calculated from the ESR spectra of Cu(II) complexes.
