Hydrothermal synthesis, crystal structure and fluorescent properties of a novel 1D polymer: VO2(C7H3O4N)Ag(C10H8N2)·H2O

The hydrothermal synthesis of V2O5, AgNO3, pyridine-2,6-dicarboxylic acid (H2pdc) and 2,2′-bipyridine (bpy) in water at 160 °C for 4 days yields a novel 1D coordination polymer VO2(C7H3O4N)Ag(C10H8N2)·H2O (1). Each V center chelates to a tridentate ligand pdc2− and coordinates to two O atoms, while the square based pyramid conformation of Ag center consists of three O atoms and a bpy molecular. V and Ag polyhedra alternate by either carboxyl or oxo bridges to further form a unique 3d–4d heterometal-based 1D double-chain ribbon.
