Synthesis of Schiff base ligands C20H14N2 (OH) 2 (N, N’-bis-salicylaldehyde o-phenylenediamine) and the corresponding two new Mn (C20H14N2 (OH) (CH3OH)] ClO4 (1) and [Mn (C20H14N2O2) (C7H5O2)] CH3CN (2) (C7H5O2 is salicylaldehyde) were synthesized and their crystal structures were determined. The results show that the complex 1 belongs to the monoclinic system with unit cell parameters of a = 1.1748 (7) nm, b = 1.3985 (7) nm, c = 1.3538 (4) nm, β = 92.63 ° and V = 2.222 2) nm3, space group P21 / n and Z = 4. Complex 2 also belongs to the monoclinic space group P21 / n with cell parameters of a = 1.0252 (2) nm and b = 2.0146 , c = 1.2494 (4) nm, β = 111.12 (2) °, V = 2.407 (2) nm3 and Z = 4. UV-vis spectra show that complexes 1 and 2 have an absorption at 584 nm and 592 nm, respectively, belonging to the d d transition spectrum of Mn III.
