Synthesis and spectroscopic studies of a new unsymmetrical ligand, N(E),N′(E)-bis[(E)-2-methyl-3-phenylallylidene]propane-1,2-diamine, and its zinc complexes

Abstract

A new unsymmetrical bidentate Schiff base N(E),N′(E)-bis[(E)-2-methyl-3-phenylallylidene]-propane-1,2-diamine and four zinc complexes with general formula Zn(BMPAPD)X₂ in which X = Cl⁻, Br⁻, I⁻, or SCN⁻, have been prepared and characterized by elemental analysis, mass spectrometry, ¹H NMR (Nuclear Magnetic Resonance), ¹³C NMR, Fourier Transform–Infrared and Ultraviolet–Visible spectra, and molar conductance. All compounds are nonelectrolytes in dimethyformamide. The molar conductance and spectral properties indicate coordination of halides and thiocyanate ions to zinc in pseudo-tetrahedral geometry.
