Crystal structures of amminehalocobalt(III) compounds with di‐ or trithionate anions have been determined in order to know whether they interact to adopt specific molecular packing patterns and whether di‐ and trithionate anions undergo the S–S bond cleavage reactions as has been found for the S 4 O 6 2– ion. In the structures of p ‐[Co(tren)(NH 3 )Cl]S 2 O 6 ·H 2 O ( 1 ) and t ‐[Co(tren)(NH 3 )Cl]S 2 O 6 ( 2 ), the configurational differences in the cations dictate the hydrogen‐bonding pattern with the dithionate anion to lead to racemic structures. cis ‐[Co(en) 2 (NH 3 )Br]S 3 O 6 ( 3 ) also crystallizes in a racemic space group P 2 1 / c in which the ions form a macrocyclic hydrogen‐bonded network. Aqueous solutions of S 3 O 6 2– and p ‐[Co(tren)(NH 3 )Cl] 2+ produce p ‐[Co(tren)(NH 3 )(OSO 3 )]ClO 4 ( 4 ) which is believed to be derived from the hydrolytic cleavage of S–S bond in the trithionate anion. These results reinforce our previous observation of the S–S cleavage reactions for the tetrathionate anion.
