A novel complex of [Mn(H2O)6](4-OPA)2·2H2O (4 - OPA - = 4 - oxo - 1 (4H) - pyridineacetate ) was synthesized by the reaction MnCl2 ·4H2O and 4 -oxo -1 (4H) -pyridineacetic acid in an aqueous solution, and characterized by elemental analysis, IR spectrum and single crystal X- ray diffraction. The title complex belongs to monoclinic system with space group P21/c, a=1.2561(3)nm,b=1.2949(3)nm,c=0.68547(14)nm,β=98.68(3)°.V=1.1022(4)nm^3,Z=2,Mr=503.32. R=0.0319,ωR=0.0827 The gn(Ⅱ) atom resided in the inversion center is coordinated by six water molecules, having a nearly ideal octahedron geometry. The 4 - oxo - 1 (4H) - pyridineacetate anion acts as counter - ion. Furthermore, a three - dimensional H - bonding supramolecular framework is contrusted by intramolecule hydrogen bonds and eletrostatic interactions between the anions and cations.
