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 chloride of this oxidation state is formed only with difficulty and decomposes readily into lead(II) chloride and chlorine gas. The bromide and iodide of lead(IV) are not known to exist. [3] Lead dioxide dissolves in alkali hydroxide solutions to form the corresponding plumbates. [2] PbO 2 + 2 OH − + 2 H 2 O → Pb(OH) 2− 6
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 chloride may refer to: Lead(II) chloride (plumbous chloride), mineral name: cotunnite. Lead(IV) chloride (plumbic chloride) Hexachloroplumbate(IV) (dianion)
Less common lead oxides are: Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow; Pb 12 O 19, monoclinic, dark-brown or black crystals; The so-called black lead oxide, which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries

Few inorganic lead(IV) compounds are known. They are only formed in highly oxidizing solutions and do not normally exist under standard conditions. [76] Lead(II) oxide gives a mixed oxide on further oxidation, Pb 3 O 4. It is described as lead(II,IV) oxide, or structurally 2PbO·PbO 2, and is the best-known mixed valence lead compound.
Polonium tetrachloride (also known as polonium(IV) chloride) is a chemical compound with the formula Po Cl 4. The salt is a hygroscopic bright yellow crystalline solid at room temperature. Above 200 °C, it tends to decompose into polonium dichloride and excess chlorine, similar to selenium tetrachloride and tellurium tetrachloride. [1]
