A reaction product formed by degradation of lead in a water-saturated atmosphere containing formaldehyde and sulfur dioxide has been characterized by IR spectroscopy and X-ray diffraction. The IR spectra indicated that the compound is a salt of hydroxymethanesulfonic acid containing water, and the crystal structure determination shows the compound to be aquabis(hydroxymethanesulfonato)lead(II), which crystallizes in P2(1)/c with Z = 4. At 122 K the cell dimensions are a = 5.471(1), b = 17.679(3), c = 9.481(1) angstrom and beta = 91.93-degrees(2). The structure was refined to R = 0.024 using 4095 observed reflections. The lead atom is surrounded by nine coordinating oxygen atoms, coming from the water molecule and five different anions, which form five- and four-membered chelate rings. A comparison is made with other lead(II) complexes having organic oxygen ligands. The crystal packing is determined by the lead-oxygen interactions and hydrogen bonds forming a three-dimensional network.
