(a) A pair of S2O32– anions in Na2S2O3·2H2O connected by two H2O mol­ecules via hydrogen bonds. (b) Illustration of the hydrogen-bond network between thio­sulfate anions, drawn as tetra­hedra, and water mol­ecules in Na2S2O3·2H2O: two S2O3 tetra­hedra (e.g., the blue ones) are bonded by two H2O (blue) to form dimers, which are connected by two H2O (pink) with another dimer (green). These tetra­meric units are inter­connected by H2O with neighbouring tetra­mers (yellow and red tetra­hedra).
