Crystal structure of cis-tetra­aqua­dichlorido­cobalt(II) sulfolane disolvate

In the title compound, [CoCl(2)(H(2)O)(4)]·2C(4)H(8)SO(2), the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol­ecules and two adjacent chloride ligands in a slightly distorted octa­hedral coordination environment. The cisoid angles are in the range 83.27 (5)–99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packing can be described as a linear arrangement of complex units along c formed by bifurcated O—H⋯Cl hydrogen bonds between two water mol­ecules from one complex unit towards one chloride ligand of the neighbouring complex. Two solvent mol­ecules per complex are attached to this infinite chain via O—H⋯O hydrogen bonds in which water mol­ecules act as the hydrogen-bond donor and sulfolane O atoms as the hydrogen-bond acceptor sites.
