| Abstract: Three transition metal complexes based on H4ddb ligand, namely[Co2(ddb)(phen)2(H2O)6]·3H2O (1),[Co(ddb)0.5(bpy)0.5(H2O)3]n (2) and {[Ag(dpe)]·0.5(H2ddb)·H2O}n (3). (H4ddb=3,3',4,4'-tetracarboxyazobenzene, bpy=4,4'-pyridine, dpe=1,2-di(4-pyridyl) ethylene) have been synthesized and structurally characterized by elemental anal-yses, IR spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction analyses. Complex 1 is binuclear structure, which is linked into 3D supramolecular network through rich hydrogen bonding interactions. Complex 2 shows 2D network constructed from Co2+ ion cross-linked by ddb4- ligands via μ4:η1,η1,η1,η1 coordina-tion mode. Complex 3 is linear chain structure based on Ag(Ⅰ) ion and dpe ligands. Interestingly, the guest molecule H2ddb2- extends a 3D supramolecular structure of 3 through intermolecular hydrogen bonding interactions. In addition, the thermal stabilities and luminescence properties of 1~3 were also studied. |
