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 St. Louis version of "'Hill Brothers Self Service Shoe Store'" went from 3 to 103 stores in the Midwest and South between 1956 and 1971.
