Abstract
The NiII 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.
