PbCl 2 is used in synthesis of lead(IV) chloride (PbCl 4): Cl 2 is bubbled through a saturated solution of PbCl 2 in aqueous NH 4 Cl forming [NH 4] 2 [PbCl 6]. 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 ...

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]

Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
