Abstract
The title compound, [Co(H2O)6](CH3C6H4SO3)2, has a structure where the metal atom is surrounded by six molecules of water forming the cation and the anion is deprotonated 4-toluenesulfonic acid. The Co atom is in a nearly regular octahedral coordination geometry, with Co—O distances between 2.0529 (14) and 2.0810 (16) Å, and angles ranging from 87.25 (9) to 92.75 (9)°. The supramolecular structure consists of parallel layers of cations and anions. The anions are arranged with their sulfonate groups directed towards the cation layer in an alternating fashion and form hydrogen bonds with the water molecules of the cation.
