The title compound was successfully synthesized by the simple hydrothermal route. Interestingly, the title compound exhibits a rare two-coordinated linear N-Cu-N configuration around cuprous ions. Furthermore, the title compound is stacked via hydrogen-bond assembly in three dimensions to form the supermolecule with a channel of 3.98(5) x 8.81 (1) angstrom along the b axis, which may be useful in studying the porous coordination materials.
