摘要

The hydrothermal synthesis Of V2O5, Ag2O and H2L (H2L = pyridine-2,6-dicarboxylic acid) in water at 180 degreesC for 72 It 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.
