In the title compound, C16H8N6O2S2·2C2H6OS, the phenanthroline mol­ecule resides on a twofold axis, and the asymmetric unit also contains a slightly disordered [occupancy ratio for S atom of 0.95 (3):0.047 (3)] mol­ecule of dimethyl sulfoxide. The O atoms of the solvent mol­ecule accept hydrogen bonds from the N—H groups of the five-membered 2,3-di­hydro-1,3,4-oxa­diazole-2-thione ring. This ring is nearly coplanar with the phenanthroline ring, with a dihedral angle between their least-squares planes of 8.86 (6)°. In the crystal, the mol­ecules are linked by C—H⋯O inter­actions.
