摘　　要：Two isostructural inorganic-organic hybrid M（II）–Nb（V） oxyfluorides, namely, M（H2O）2（pyz）NbOF5 （M=Co 1, Cu 2; pyz=pyrazine） have been hydrothermally synthesized and structurally characterized. Both compounds possess two-dimensional layer structure constructed by neutral M（H2O）2NbOF5 chains inter-connected via bridging pyrazine ligands. The structure is further extended into three-dimensional supramolecular architecture through inter-layer H-bonding interactions between the coordinated water molecules and fluorine ions. The luminescent properties and thermal stability of both compounds have been investigated.Two isostructural inorganic-organic hybrid M（II）–Nb（V） oxyfluorides, namely, M（H2O）2（pyz）NbOF5 （M=Co 1, Cu 2; pyz=pyrazine） have been hydrothermally synthesized and structurally characterized.
