Lead (II) bromide is a lead salt which is used in the electronics industry and which is produced from 1,2-dibromoethane and tetraethyl lead when leaded gasoline is burned .

properties

Lead (II) bromide shows photoluminescence under UV light at low temperatures (<200 K). It crystallizes orthorhombically , space group Pmnb (space group no. 62, position 2) , with the lattice parameters a = 4.71 Å , b = 8.02 Å, c = 9.48 Å. Template: room group / 62.2

use

Lead (II) bromide is used in the electronics industry as a thin-film material. It can also be used for the electrolytic generation of lead (e.g. as a school experiment) and as a starting material for complex compounds .
