In the title compound, [Cu(NO3)2(C8H9N3)2], the CuII atom, lying on an inversion center, has a distorted octahedral coordination environment defined by four N atoms from two chelating 2-aminomethyl-1H-benzimidazole ligands and two O atoms from two monodentate nitrate anions. In the crystal, N—H⋯O hydrogen bonds link the complex molecules into a three-dimensional network. An intramolecular N—H⋯O hydrogen bond is also observed.
