    • Synthesis of N-propionyl-3-hydroxy-2-naphthoylhydrazide: The ligand H3 pnhz was prepared as follows: 0.97 g (10.5 mmol) of propionyl chloride was added to 70 mL of chloroform solution at 0°C containing 1.6 mL (11 mmol) of triethylamine and 0.72 g (10 mmol) of propionic acid under stirring. The solution was slowly brought to ambient temperature. An equivalent amount of 3-hydroxy-2-naphthoichydrazide (2.02 g, 10 mmol) was added to the solution and refluxed for 24 h. The white precipitate obtained was filtered and washed with small quantities of cold chloroform. Yield: 2.39 g (92.9, M.p. 268-270 °C. Elemental analysis, ) for C14H14N2O3 (320, calcd.

    • Synthesis of complex 1: This complex were obtained through the following methods: (1) The H3 pnhz (0.051 g, 0.2 mmol) was dissolved in 10 mL of DMF and Mn(OAc)2 4H2 O (0.049 g, 0.2 mmol) was slowly added in the solid form without stirring. The black crystals appeared after the solution had stood for two weeks. Yield: 0.049 g (67, based on Mn(OAc)2·4H2O, 2) The solution of Mn(OAc)2·4H2O (0.049 g, 0.2 mmol) in methanol (10 mL) was added to the mixture of H3pnhz (0.051 g, 0.2 mmol) and 1,2-bis (4-pyridyl)ethane (0.0184 g, 0.1 mmol) in DMF (10 mL, After stirring three hours, dimethyl ether was diffused into the filtrate. After the solution had been standing for 5 days, the crystals suitable for X-ray diffraction study appeared. Yield: 0.060 g (82, based on Mn(OAc)2·4H2O. Elemental analysis, ) for C192H198Mn12N32
