In the title complex, [CuCl(C14H12N4)2], the CuI atom, lying on a twofold rotation axis, is coordinated by two N atoms of two 1,2,3,4-tetra­hydro-1,4,6,11-tetra­aza­naphthacene ligands and one Cl atom, also lying on the twofold rotation axis, in a distorted trigonal-planar geometry. The complex mol­ecules are connected into a one-dimensional structure along [001] via N—H⋯N hydrogen bonds and further into a three-dimensional structure via N—H⋯Cl hydrogen bonds. π–π inter­actions between the pyrazine and benzene rings and between the benzene rings [centroid–centroid distances = 3.5635 (15) and 3.9128 (16) Å] are present.
