Cu2(C3H2N3O3)2(C10H8N2): A Hydrogen-bonded Assemblies Supermolecule Containing 1D Channels and Novel Two-coordinated Linear N–Cu–N Configurations

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) × 8.81(1) Å along the b axis, which may be useful in studying the porous coordination materials.
