　　Hydrothermal reaction of 2,5-di(2,4-dicarboxylphenyl)pyridine(ddpp)with Mn(Ⅱ)acetate in the presence of ammonium oxalate gives rise to a 3-D coordination framework {[Mn4(ddpp)2(μ4-C2O4)·6H2O]·2H2O}n(1).It has been characterized by elements analysis,thermogravimetry,variable temperature magnetic susceptibility and single-crystal X-ray diffraction study.
