An IR- and EXAFS-study of the precursor system lead(II) acetate trihydrate, dissolved in methanol and 2-methoxyethanol

The solid phase of lead(II) acetate trihydrate and a solution of this compound in methanol as a potential monodentate ligand and in 2-methoxyethanol as a potential bidendate ligand were investigated by IR- and EXAFS-spectroscopy. The structures of the lead compound in methanol and 2-methoxyethanol are identical or very similar. Lead(II) acetate trihydrate forms a subacetate in both solutions. 3Pb(OOCCH3)(2) . PbO . H2O can be isolated as precipitate in the methanolic solution at room temperature and, dissolved in 2-methoxyethanol, after refluxing the solution. (C) 1997 Elsevier Science B.V.
