Organobismuth compounds

Triphenylbismuthine is an organobismuth compound with the formula . It is a white, air-stable solid that is soluble in organic solvents. It is prepared by treatment of bismuth trichloride with phenylmagnesium bromide.

Bismabenzene () is the parent representative of a group of organobismuth compounds that are related to benzene with a carbon atom replaced by a bismuth atom. Bismabenzene itself has been synthesised but not isolated because it is too reactive, tending to instead dimerize in a Diels-Alder addition.

Pentamethylbismuth (or pentamethylbismuthorane) is an organometalllic compound containing five methyl groups bound to a bismuth atom with formula Bi(CH3)5. It is an example of a hypervalent compound. The molecular shape is trigonal bipyramid.
