In the crystal structure of the title compound, [Ag2(N3)2(C2H8N2)], the Ag atoms of adjacent polymeric AgN3 chains are bridged by the 1,2-di­amino­ethane ligand to furnish a ribbon structure. The Ag atom shows trigonal planar coordination. The 1,2-di­amino­ethane ligand lies on an inversion center.
