The results of the electronic spectra and magnetic susceptibility measurement were used to assign various geometries to the complexes. The data obtained from the electronic spectra was presented in Table while the results obtained for the magnetic moment and conductance measurements were presented in Table . The ligands exhibited electronic absorption bands due to π→π* and n→π* transitions ascribed to the presence of aromatic ring and electronegative atoms in the ligand, mostly from C=C and C=N respectively. The bands at 229 and 247, and 344 nm in the ultraviolet spectrum of the ligand was assigned to n→π* and π→π* transitions respectively. These bands were seen at lower or higher wavelengths in the spectra of the metal complexes because of electronic changes due to coordination of the ligand to the metal ions . The visible region of the electronic spectrum of the nickel complex gave a band at 414 nm due to 1 Ag → 1 Eg transition which is characteristic of a square planar geometry . The assignment of this geometry was supported by the magnetic moment value of 0.14BM since a moment less than 1BM is expected for nickel complex in a square planar environment . The visible spectrum of the cobalt complex gave a band at 405 nm due to 4 A2→ 4 T1(F) transitions (Table ), which is characteristic of a tetrahedral geometry. The assignment of this geometry was supported by a magnetic moment value of 4.35BM. The µeff of Co(II) complexes are expected to be higher than spin-only value for tetrahedral complexes due to orbital contributions and could be within the range 4.20-4.60 B.M .
