The reaction of tetrasodium calix[4]arenesulfonate with lead(II) nitrate gi
ves a complex with 2:1 metal-ligand stoichiometry. The complex has been cha
racterized by elemental and X-ray crystal structure analysis. The latter re
veals a layered structure consisting of alternating hydrophilic and hydroph
obic layers. All Pb(II) ions have different coordination environments and s
how an unusually high degree of hydration in the solid state. (C) 1999 Else
