Synthesis, crystal structure, spectral and thermal characterization of bis(o-vanillinato)-triethylenglycoldiiminecopper(II) and bis[(R)-(−)-hydroxymethylpropylimine o-vanillinato]copper(II)

The novel complexes, bis(o-vanillinato)-triethyleneglycoldiiminecopper(II) (1) and bis[(R)-(−)-hydroxymethylpropylimine o-vanillinato]copper(II) (2) were synthesized and characterized by elemental analysis, magnetic susceptibility, spectral methods (UV-Vis and FT-IR), simultaneous TG, DTA techniques and X-ray diffraction. The crystal structures of (1) and (2) determined as: Cu atom is coordinated by two imine N atoms and two phenol O atoms from the Schiff base ligand in a slightly distorted square-planar coordination.
