摘　　要：Two new supramoleeular polymers [ M （2-NH2 py）2 （ox） ] [ M = Co （1）, Ni （2） ; 2-NH2py = 2-aminopyridine; ox = oxalate ] were hydrothermally synthesized and characterized by elemental analyses, IR and single-crystal X-ray diffraction analyses. The isomorphic compounds 1 and 2 both possess one-dimensional zigzag chain structures, which are composed of [ M （2-NH2 py）2 ]^2＋ units bridged by tetradentate oxalate ligands to form three-dimensional supramolecular network v/a the C-H…O hydrogen bonds and π-π stacking interactions. Compound 1 displays antiferromagnetie interaction.Two new supramoleeular polymers [ M （2-NH2 py）2 （ox） ] [ M = Co （1）, Ni （2） ; 2-NH2py = 2-aminopyridine; ox = oxalate ] were hydrothermally synthesized and characterized by elemental analyses, IR and single-crystal X-ray diffraction analyses.
