Two-dimensional hydrogen-bonded networks based on bent oxadiazole bridging organic spacers

The synthesis, single crystal structures and luminescent properties of two hydrogen-bonded two-dimensional porous compounds (1 and 2) based on bent oxadiazole-containing organic spacers, namely 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L1) and 2,5-bis(3-pyridyl)-1,3,4-oxadiazole (L2), are reported. image and image anions are located in square- (1) and rhombus-like (2) channels as the guests, respectively.
