Abstract

Three transition metal complexes derived from the condensation product of (9E)-N-(E)-(benzylimino)methylidene phenylmethan amine with phthalaldyde and benzyl amine have been synthesized and characterized. The geometries of the isolated chelate compounds were investigated by physical, elemental analyses (CHN), conductance, molar susceptibility, mass spectra, ¹H-NMR, FTIR and electronic spectra data. The elemental analyses showed that the isolated chelates have 1:1 [M:L] ratio. The values of conductance showed that the all the chelates are electrolytic in nature except the compound with the formula, [CuL(H₂O)₂Cl₂].2H₂O, which is non-electrolytic. Also, the results of spectral and the values of magnetic moments of the Cr³⁺, Ni²⁺ and Cu²⁺ chelates exhibit that the compounds are paramagnetic in nature and characterized by octahedral geometries. The IR spectral data displayed the main coordination sites on coordination toward lower wavenumbers .
