The pyramidal nature indicates the presence of a stereochemically active lone pair of electrons. [15] The PbC bond energies in TML and TEL are only 167 and 145kJ/mol; the compounds thus decompose upon heating, with first signs of TEL composition seen at 100C (210F). In case of high dose, the victim experiences a metallic taste, chest pain, and abdominal pain. Lead oxide (PbO), lead-contg. [6] Both allotropes are black-brown in color and always contain some water, which cannot be removed, as heating also causes decomposition (to PbO and Pb3O4).
