This work reports the syntheses, crystal structures and properties of two mononuclear Mn(III)-Schiff base complexes, [Mn(III)(L1)(H2O)]ClO4·2H2O 1 and [Mn(III)(L2)]ClO4·2H2O 2. X-ray crystallographical structure analysis confirms that the crystal of 1 belongs to the orthorhombic crystal system and Pna21space group. Its cell parameters are a= 10.932(7)Å, b= 22.393(5)Å, c= 8.960(3) Å, V=2193(I)Å3, Z=4. Crystal of 2 belongs to the same crystal system and P212121space group. Its cell parameters are a= 17.345(3)Å, b= 17.905(2)Å, c= 7.789(1)Å, V= 2418.9(6)Å3, Z= 4. Electrochemical measurements show that complex 2 is a more stable electrochemical product and complex 1 is more sensitive to the external electric field, by which the coordination environment is confirmed to be a decisive factor in the determination of the stability of compound.
