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

摘要

The hydrothermal synthesis of V_2O_5,Ag_2O and H_2L (H_2L=pyridine-2,6-dicarboxylic acid) in water at 180 deg C for 72 h yields a novel 2D coordination polymer [VAgLO_2]_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.
