Abstract: The Ni^II centre in the cation of the title compound, [Ni(C₆H₁₂S₃)₂]Br₂·4H₂O, occupies a crystallographic inversion centre and is octahedrally coordinated by six S-donors from two [9]aneS₃ ligands. Ni-S distances range from 2.3749 (16) to 2.4077 (15) Å and S-Ni-S angles where both thia donors belong to the same ligand lie in a narrow range between 88.09 (5) and 88.67 (6)°. The water molecules participate in extensive hydrogen bonding with each other and with the Br^- anions to form double chains with eight- and 12-membered hydrogen-bonded rings running along the crystallographic a direction.
