摘　　要：The title compound of o-vanillin ethylene diamine Schiff base monoacetic acid manganese(Ⅱ) monohydrate, Mn((CH3 OC6 H3 OCHNC2H4NCHC6H3OO-CH3) (H2O) (CH3COOH). CH3OH. 2H2O, was synthesized and its crystal structurewas determined by X-ray diffraction methed. Crystal data are: Mr = 527. 43, monoclinic system, space group C2/c, Z= 8 F a= 17. 720(4), b= 12. 584(3), c= 22. 648(5)A, β= 112. 61 (3)°； V=4662(4) A, Dx=1. 503 g/cm3, μ=5. 99 cm-1, F(000) =2216. The final agreement factors are R= 0. 053 and Rw= 0. 056 for 2208 unique refiections (I>3σ(I) )- The manganese(Ⅱ) is coordinated to N(1), N (2), O(2) ) O(3) of Schiff base ligand, O atom of water and O(11) of acetic acid. They formed adistorted octahedral structure. Each asymmetry contains one solvent methanol moleculeand two solvent water molecules.The title compound of o-vanillin ethylene diamine Schiff base monoacetic acid manganese(Ⅱ) monohydrate, Mn((CH3 OC6 H3 OCHNC2H4NCHC6H3OO-CH3) (H2O) (CH3COOH).
