【Abstract】 Two coordination supramolecules,[Co(phen)2(L)]NO3·4H2O [L=CH3COO(1) and NH2COO(2)],have been solvothermally synthesized and structurally characterized by X-ray diffraction and spectroscopy.Both complexes are self-assembled through hydrogen bond from [Co(phen)2L]2+,NO-3 and H2O.The main structure feature for two complexes is presence of 1D chain in(1) and 2D layer in(2) constructed by hydrogen bonds from NO-3 and water molecule.The weak interaction of C—H…O and N—H…O links the cation of [Co(phen)2L]2+ and the chain or layer,leading into the 3D supramolecule.In addition,the photo-physical property of two complexes is discussed.更多还原
