Poly[diaqua(μ3-8-oxidoquinoline-5-sulfonato-κ4N,O8:O5:O8)nickel(II)]

Abstract

In title compound, [Ni(C9H5NO4S)(H2O)2]n, the NiII atom is coordinated by one N atom and two bridging O atoms from two 8-oxidoquinoline-5-sulfonate ligands, one sulfonate O atom from a third ligand, and two water molecules in a distorted octahedral geometry. The two NiII atoms are linked to each other through the bridging O atoms, forming a dimer. Adjacent dimers are connected through the coordination of the sulfonate O atom into a two-dimensional coordination network parallel to (010). Hydrogen bonds between the coordinated water molecules and the uncoordinated O atoms of the sulfonate groups result in the construction of a three-dimensional supramolecular structure.
