Lead tetrachloride, also known as lead(IV) chloride, has the molecular formula PbCl 4. It is a yellow, oily liquid which is stable below 0 °C, and decomposes at 50 °C. [2] It has a tetrahedral configuration, with lead as the central atom. The Pb–Cl covalent bonds have been measured to be 247 pm and the bond energy is 243 kJ⋅mol −1. [4]

The latter is reacted with cold concentrated sulfuric acid (H 2 SO 4) forming PbCl 4 as an oil. [10] Lead(II) chloride is the main precursor for organometallic derivatives of lead, such as plumbocenes. [11] The usual alkylating agents are employed, including Grignard reagents and organolithium compounds: 2 PbCl 2 + 4 RLi → R 4 Pb + 4 LiCl + Pb
Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it causes lead poisoning. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(OAc) 2 ·3H 2 O, a colourless or white efflorescent monoclinic crystalline substance.
