Abstract: In the title compound, [Cu(C₈H₉N₅)₂](C₂N₃)₂, the Cu complex cation and dicyanamide anions lie on a twofold axis. Discounting the weak coordination of a dicyanamide anion, the Cu^II atom is coordinated by four N atoms from two 2-guanidinobenzimidazole ligands in a tetrahedrally distorted square-planar geometry. The cations and anions are linked via N-HN hydrogen bonds, forming a two-dimensional network parallel to (010).
