Hydrothermal synthesis, crystal structure and luminescent properties of 2d grid-like polymer based on 3d–4d mixed metals

The hydrothermal synthesis of V2O5, Ag2O and H2L (H2L = pyridine-2,6-dicarboxylic acid) in water at 180 °C for 72 h yields a novel 2D coordination polymer [VAgLO2]n (1). Each V center chelates to a tridentate ligand L, while the tetrahedral conformation of Ag center consists of four O atoms. V and Ag polyhedra alternate by either carboxyl or oxo bridges to further form a unique 3d–4d heterometal-based 2D grid motif.
