The reactions of Co（NO3） 2.6H20, 1, 10-phenanthroline and phthalic acid in NaOH solution with pH 7.0 yields a new 2D supramolecular compound [ Co（C8H4O4） （CI2HsN2） （H2O） 3]· H2O. The complex has been characterized by elemental analysis, IR, and single crystal X-ray diffraction analysis. It crystallized in the monoclinic space group P2（1）n,a=0.7571（2）nm,b=1.3737（3）nm,c=2.0015（4）nm,β=95.56（1）°,V=2.0719（8）nm^3,Mr=475.31,Dc=1.524g/cm^-3,Z=4,F（000）=980,μ（MoKα）=0.879mm^-1,. The final Rland wR2 are 0. 034 8 and 0.071 1 respectively. The cobalt（ Ⅱ ） ion is six-coordinated in a distorted octahedron to form a unit. Every unit is connected by hydrogen bonds forming 1D chain and 2D supramolecular network by π - π stacking interaction between adjoining chains.
