摘　　要：The title complex [Mn(phen)2(H2O)2](OAc)26H2O (phen = 1,10-phenanthroline, C12H8N2, OAc = acetate, C2H3O2) with formula C28H38MnN4O12 and Mr = 677.56 has been syn- thesized and structurally characterized by X-ray diffraction. The crystal is of triclinic, space group P ?with a = 9.6201(5), b = 13.4663(7), c = 14.5375(8) , a = 108.428(1), b =93.898(1), g = 110.492(1), V = 1639.5(2) ?, Dc = 1.373 g/cm3, F(000) = 710, = 0.468 cm-1 and Z = 2. The final refinement gave R = 0.0522 and wR = 0.1259 for 4714 observed reflections with I > 2s(I). It consists of discrete [Mn(phen)2(H2O)2]2+ cation, two acetate anions and six lattice water molecules. The MnII ion coordinated by four nitrogen atoms from two chelating phen and two oxygen atoms from two cis-related water molecules is in a distorted octahedral coordination environment. Two OAc- anions and six water molecules exist outside the [Mn(phen)2(H2O)2]2+ cation as counter ions and solvate molecules, respectively. The cations and anions are interconnected by the solvate water molecules which are hydrogen bonded to both aqua ligands and acetate oxygen atoms, building up the crystals of this compound to be a supramolecule-like aggregate.
