Unit 15:Organometallics
105.1.4 Pb, Sb, Sn, Hg
105.2 Transition-metal organometallic chemistry.
The organometallic chemistry of the transition elements is quite different from the main-
group ones due to the availability for bonding of then dorbitals with consequent ability
for the central atom to change geometry and expand the octet.
