    Notes: K[Co(tren)(NH3)(SO4)](S4O6)·2(H2O) (1) and [cis-α-Co-(trien)(NH3)Cl](S5O6) (2) have been prepared unexpectedly while attempting to obtain crystals suitable for X-ray diffraction of [Co(tren)(NH3)Cl](S4O6) (3) and of [cis-Co(trien)(NH3)Cl](S4O6) (4), respectively. 1 is derived from 3 by hydrolysis of the tetrathionate anion resulting in a sulfato moiety which displaces the chloro ligand from the coordination sphere of the metal center. 2 is derived from 4 by hydrolysis of the tetrathionate anion followed by reformation into pentathionate anion and H2S, as described in previous chromatographic work by Steudel. Compounds 1 and 2 have been characterized by elemental analyses and by single-crystal X-ray diffraction studies.

    The Interaction between Amminehalocobalt(III) Cations and Polythionate Anions: Hydrogen-Bonding Patterns and S-S Bond Cleavage Reactions (2000)

    Notes: 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 S4O62- ion. In the structures of p-[Co(tren)(NH3)Cl]S2O6·H2O (1) and t-[Co(tren)(NH3)Cl]S2O6 (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(NH3)Br]S3O6 (3) also crystallizes in a racemic space group P21/c in which the ions form a macrocyclic hydrogen-bonded network. Aqueous solutions of S3O62- and p-[Co(tren)(NH3)Cl]2+ produce p-[Co(tren)(NH3)(OSO3)]ClO4 (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.
