摘　　要：A dinuclear manganese（Ⅱ） complex, [Mn2（μ-OAc）2（phen）4]（ClO4）2 1 （phen = phenanthroline）, has been prepared by the reaction of Mn（OAc）2-4H2O, phen, tartaric acid and NaClO4·H2O in MeOH/H2O solution. The crystal structure has been determined by X-ray diffraction. The crystal is of monoclinic, space group P21/c with a = 9.6052（4）, b = 14.2353（7）, c = 18.8893（8） A, β= 96.584（1）° C52H38C12Mn2N8O12, Mr = 1147.68, V= 2565.8（2） A^3, Dc = 1.486 g/cm^3, F（000） = 1172,μ = 0.668 cm^-1 and Z = 2. The final refinement gave R = 0.0605 and wR = 0.1619 for 3203 reflections with I 〉 2σ（I）. The complex contains a dinuclear [Mn2（μ-OAc）2（phen）4]]^2＋ cation located at a centre of symmetry with two syn-anti acetate bridges between the Mn atoms. Each Mn atom is coordinated by four N atoms from two chelating phen ligands and two O atoms from a pair of bridging acetate groups to furnish a distorted octahedral geometry. Two ClO4 anions exist around the cation [Mn2（μ-OAc）2（phen）4]^2＋ as counter ions.A dinuclear manganese（Ⅱ） complex, [Mn2（μ-OAc）2（phen）4]（ClO4）2 1 （phen = phenanthroline）, has been prepared by the reaction of Mn（OAc）2-4H2O, phen, tartaric acid and NaClO4·H2O in MeOH/H2O solution.
