Salts and Esters of 1,2-Hydrazin-bis(thiocarboxylic)acid. Crystal Structures of K2[OSC—N2H2—CSO] · 2 H2O, CH3S—CO—N2H2—CO—SCH3, and CH3O—CS—N2H2—CS—OCH3 at 140 KThe anion [OSC—N2H2—CSO]2- and the molecules CH3S—CO—N2H2—CO—SCH3 and CH3O—CS—N2H2—CS—OCH3 exhibit nonplanar structures in the solid state. The dihedral angles beetween either of the two strictly planar R—CX—NH groups of each molecule are 78.8°, 77.5°, and 104.5°, respectively. The N—N bond lengths are 138.5 pm in all three compounds. The N—H groups participate in hydrogen bonds.
Notes:
Das Anion von K2[OSC—N2H2—CSO] · 2 H2O, sowie die Moleküle CH3S—CO—N2H2—CO—SCH3 und CH3O—CS—N2H2—CS—OCH3 besitzen im festen Zustand nichtplanare Konformationen. Die Diederwinkel zwischen den beiden jeweils planaren Molekülhälften betragen 78,8°, 77,5° bzw. 104,5°. Die N—N-Bindungslänge beträgt übereinstimmend in den drei Verbindungen etwa 138,5 pm. Die N—H-Gruppen sind an Wasserstoffbrückenbindungen beteiligt.
