Abstract: Three novel complexes, namely {[Zn3(L)2(SO4)2(H2O)4]·H2O}n (1), {[Cd2(L)2(SO4)(H2O)]·H2O}n (2) and {[Cd(L)I]·CH3OH}n (3). (HL=N'-nicotinoylpyrazine-2-carbohydrazonamide), have been synthesized and character-ized by elemental analyses, infrared spectra and single-crystal X-ray diffraction analyze. In complex 1, Zn(Ⅱ) ions are connected by μ3,η1η1η1-SO42- anions to form a inorganic layer motif in bc plane, and the L- ligands are decorated on both sides of the layer. Adjacent layers are connected by hydrogen-bonding interactions giving rise to 3D supramolecular network. The 2D complex 2 is formed by the[(Cd2)2(μ2-SO4)2] units and Cd1 ions which are connected by the ligands. Adjacent layers of 2 are extended into 3D supramolecular network by π…π interactions. Zigzag 1D chains of complex 3 are connected by intermolecular hydrogen bonds into extended plane structure. The photocatalytic degradation of methylene blue (MB) results indicate that complexes 1~3 are excellent candidates as photocatalysts in decomposing MB with the presence of H2O2. In addition, the luminescent properties of these three complexes have been studied in the solid state. |
