For example, combining lead nitrate and pentaethylene glycol (EO5) in a solution of acetonitrile and methanol followed by slow evaporation produces a new crystalline material [Pb(NO3)2(EO5)]. There is no evidence for the formation of the hydroxide, Pb(OH)2, in aqueous solution below pH 12. It commonly occurs as a colorless crystal or white powder and, unlike most other lead (II) salts, is soluble in water.
