Abstract: The heaviest analogues of alkynes are investigated to realize a short triple bond between Pb atoms. For a short double bond between Pb atoms, the Pb2 molecule stabilized by dative N-heterocyclic carbenes is investigated. For unsupported and supported short bonds between transition metals, two-coordinate transition-metal and bicyclic four-membered ring complexes are investigated.
