Two novel complexes [Cu(dafo) 2(H 2O) 2](NO 3) 2 and [Zn(dafo) 2(H 2O) 2](NO 3) 2 were synthesized. Their structures were determined by single crystal X-ray diffraction analysis. The crystal structure data indicate that the Cu(II) and Zn(II) ions are coordinated with the four nitrogen atoms from the two ligands (dafo) and two oxygen atoms from the two water molecules, respectively. The two ligands (dafo), Cu(II) and Zn(II) ions are in the same plane, the two water molecules are vertical to the plane, the Cu(II) ion is at the center of the malformed octahedron, and Zn(II) ion is at the center of the normal octahedron. The constitutes of the two complexes were proved by elemental analysis, IR spectra and thermal analysis. On the basis of the experimentation, the two complexes were computed by DFT-B3LYP/LANL2DZ in Gaussian-98w.
