Thermal, magnetic and electrochemical properties of polymeric copper complexes of 2-hydroxy-l,4-naphthoquinone and its methyl derivative

摘要: The reaction of 2-hydroxy-1, 4-naphthoquinone (Lawsone; Lw) and 3-methyl-2-hydroxy-1, (Phthiocol; Phth) with anhydrous CuCl 2 results in [Cu(Lw) (NH 3 ) ](M-1) [Cu(Phth) )].2H O (M-2) complexes respectively. Thermal, magnetostructural electrochemical studies indicate the polymeric nature both complexes. energy activations calculated from thermogramms is found to be 65 kJ/Lw, 23.75 kJ/NH M-1 178.90 kJ/H O, 221.5 , 566.2 kJ/Phth 28.19 kJ/ Phth M-2. increasing decreasing Χ m .T decrease temperature M-2 reveals ferro antiferromagnetic interactions cyclic voltammetry occurrence effective metal ligand solution for
