Crystal structure of bis(1,4-diazabicyclo[2.2.2]octan-1-ium) thiosulfate dihydrate

The crystal structure of the hydrated title salt, 2C 6 H 13 N 2 + ·S 2 O 3 2− ·2H 2 O, contains a centrosymmetric cyclic motif of eight hydrogen-bonded molecular subunits. Two DABCOH + cations (DABCO = 1,4-diazabicyclo[2.2.2]octane) are linked to two water molecules and two thiosulfate anions via O—...

Description
Summary:The crystal structure of the hydrated title salt, 2C 6 H 13 N 2 + ·S 2 O 3 2− ·2H 2 O, contains a centrosymmetric cyclic motif of eight hydrogen-bonded molecular subunits. Two DABCOH + cations (DABCO = 1,4-diazabicyclo[2.2.2]octane) are linked to two water molecules and two thiosulfate anions via O—H...N and O—H...O hydrogen bonds, respectively. Two other water molecules close the cyclic motif through O—H...O contacts to the first two water molecules and to the two thiosulfate anions. A second pair of DABCOH + cations is N—H...O hydrogen bonded to the two anions and is pendant to the ring. Adjacent cyclic motifs are bridged into a block-like arrangement extending along [100] through O—H...O interactions involving the second pair of water molecules and neighbouring thiosulfate anions.
