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—HN hydrogen bonds and further into a three-dimensional structure via N—HCl 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.
