The complete dinuclear title complex, [Pb2(C2H3O2)2(N3)2(C18H12N6)2], is generated by the application of a crystallographic centre of inversion. The PbII atom is coordinated by three N atoms of the tridentate ligand, two O atoms derived from an asymmetrically coordinating acetate ligand, and two azido-N atoms derived from two asymmetrically bridging azido ligands. The metal coordination geometry can be described as a square anti-prism with one position occupied by an unseen lone pair of electrons. In the ligand, the two coordinating pyridine rings are almost co-planar with the central pyrazine ring [dihedral angles = 0.47 (17) and 0.83 (18)°], but the terminal ring is twisted [dihedral angle = 19.76 (18)°]. In the crystal, the presence of π–π inter­actions [ring centroid distance between pyridyl rings = 3.581 (2) Å] leads to supra­molecular chains along the a-axis direction.
