The reaction of sodium benzoxasulfamate (ribs) with cadmium(II) and mercury(II) sulfate in aqueous solution yield the novel complexes [Cd(nbs)(2)(H2O)(4)] (1) and [Hg(nbs)(2)(H2O)(3)] (2), respectively. The complexes were characterized by elemental analyses, IR spectroscopy and X-ray crystallography. Complex 1 is monomeric and has an octahedral arrangement in which the N-donor ribs ligands occupy the axial positions, while the water oxygen atoms form the equatorial plane. Complex 2 is polymeric and shows a pentagonal bipyramidal arrangement achieved by the bridging of the HgN2O3 units through the weak interaction of the O atoms of the nitro group. The ribs ligands also occupy the axial positions of the pentagonal bipyramid, whereas three water and two nitro oxygen atoms constitute the pentagonal plane. The crystal structure packing in both crystals is achieved by the intermolecular hydrogen bonds involving water hydrogen atoms, nitro and sulfonyl oxygen atoms.
