Poly[[diaqua(₄-3-sulfonatobenzoato)lead(II)] 4,4'-bipyridine]

C. Wagner and K. Merzweiler

Abstract: The title compound, [Pb(C₇H₄O₅S)(H₂O)₂]·C₁₀H₈N₂, crystallizes as a two-dimensional coordination polymer. Double sheets are formed by Pb²⁺ ions which are connected by ₄-bridging 3-sulfonatobenzoate groups. The coordination around the Pb atoms comprises three O atoms from carboxylate groups, two O atoms from the sulfonate group and additionally two water molecules. As a result of hydrogen bonds between 4,4'-bipyridine and water molecules attached to Pb²⁺ the double layer structure is extended to give a three-dimensional supramolecular architecture.
