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.
