Boron-lead multiple bonds in the PbB2O– and PbB3O2– clusters
Despite its electron deficiency, boron can form multiple bonds with a variety of elements.
However, multiple bonds between boron and main-group metal elements are relatively rare.
Here we report the observation of boron-lead multiple bonds in PbB2O–and PbB3O2–,
which are produced and characterized in a cluster beam. PbB2O–is found to have an open-
shell linear structure, in which the bond order of B☱ Pb is 2.5, while the closed-shell [Pb≡ B–
B≡ O] 2–contains a B≡ Pb triple bond. PbB3O2–is shown to have a Y-shaped structure …
