Abstract: In the crystal structure of the title compound, [Na4Ni(C8H3O7S)2(H2O)12]n, the NiII cation occupies an inversion centre and is coordinated by the carboxyl groups of the sulfoisophthalate trianions and water molecules in a distorted octahedral geometry. Two independent NaI atoms are connected by the carboxyl and sulfonate groups of the sulfoisophthalate ligands anions and water molecules in a distorted octahedral geometry. The sulfoisophthalate ligands and coordinated water molecules bridge the NiII and NaI cations, forming a three-dimensional polymeric structure. Weak - stacking is present between parallel benzene rings [centroid-centroid distance = 3.9349 (10) Å]. Extensive O-HO and C-HO hydrogen bonding helps to stabilize the crystal structure.
