Synthesis of Phthalato-phenanthroline-cobalt Complex and its 2D Supramolecular Structure

The reactions of Co(NO_(3))_(2)·6H_(2)O,1,10-phenanthroline and phthalic acid in NaOH solution with pH 7.0 yields a new 2D supramolecular compound Co(C_(8)H_(4)O_(4))(C_(12)H_(8)N_(2))(H_(2)O)_(3)]·(H_(2)O).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=0.757 1(2) nm,b=1.373 7(3) nm,c=2.001 5(4) nm,β=95.56(1)°.V=2.071 92(8) nm~(3),M_(r)=475.31,D_(c)=1.524 g/cm~(3),Z=4,F(000)= 980,μ(Mo Kα)=0.879 mm~(-1).The final R_(1)and wR_(2) 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.
