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

    Notizen: 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.

    Syntheses of K[Co(tren)(NH3)(SO4)](S4O6)·2(H2O) and of [cis-α-Co(trien)(NH3)Cl](S5O6) - Compounds Produced by Hydrolytic Cleavage of Sulfur-Sulfur Bonds of the Tetrathionate Anion (1999)

    Notizen: 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.

    Notizen: The reactions of sodium monooxamide (H2NCOCO2Na) with trans-[Co(en)2Cl2]Cl, trans-[Co(3,2,3-tet)Cl2]Cl (3,2,3-tet = 1,5,8,12-tetraazadodecane), cis-α-[Co(trien)Cl2]Cl and [Co(tren)Cl2]Cl result in the formation of [Co(en)2(ox)]Cl · 4H2O (1), cis-β-[Co(3,2,3-tet)(ox)]Cl· 4 H2O (2), cis-α-[Co(trien)(ox)]Cl · 2 H2O (3), and [Co(tren)(ox)](ClO4) · 0.5 H2O (4) respectively, implying a hydrolytic cleavage of the amide bond. [Co(tren)(O,O′-oxam)]Cl2 · 2 H2O (5) (oxam = H2NCOCO2-) and p-[Co(tren)(NH3)(O-oxam)]Cl2 (6) have also been prepared in order to give mechanistic information for the hydrolysis of monooxamide. Crystal structures of the products are reported and possible pathways for the hydrolysis reactions are discussed.
