In the centrosymmetric title complex, [Ni(C7H3FNO3S)2(H2O)4], the NiII atom exhibits a slightly distorted trans-NiN2O4 octahedral coordination. The nitrogen donors are provided by two 5-fluorosaccharinate ligands and the oxygen donors are provided by four water molecules. The crystal structure features O-HO and bifurcated O-H(F,O) hydrogen bonds, the latter involving the F atom of the 5-fluorosaccharinate ligand.
