Synthesis, and Spectral Studies of Demi-macrocycles of Ligand N2O2 with Ni (II) and Cu (II) Ions

The new series of demi-macrocycles of the type [C14 H30 N2 O2 (Cl2 O4) 2] having N2O2 as donors ligand were synthesized by the equimolar condensation reaction of ethane-1, 2-diamine in acetone in presenced of perchloric acid. The head unit of demi-macrocycle formed was proposed by the two acetone molecules [M (C14H30N2O2) (ClO4)2] Where, M = Ni(II) and Cu(II) were formed by the reaction of proposed demi-macrocycle with respective metal salts. The complexes formed were characterized by the elemental analysis, conductance and magnetic susceptibilities measurements, and also by spectral methods.
