Synthetic and Crystallographic Investigation of the Layered Coordination Framework Copper-1,3-bis(4-carboxyphenyl)-5-ethoxybenzene

The reaction of 1,3-bis(4-carboxyphenyl)-5-ethoxybenzene and copper acetate monohydrate yields copper-1,3-bis(4-carboxyphenyl)-5-ethoxybenzene(DMF), and upon removal of coordinated DMF molecules, copper-1,3-bis(4-carboxyphenyl)-5-ethoxybenzene is attained. The compound does not form as a traditional three-dimensional metal–organic framework and instead produces a “layered coordination framework”, where the individual layers are separated by the ethyl chains on the linker. The synthesis and crystallographic characterization of the material are described.
