Bismuthinidenes are a class of organobismuth compounds, analogous to carbenes. These compounds have the general form R-Bi, with two lone pairs of electrons on the central bismuth(I) atom. Due to the unusually low valency and oxidation state of +1, most bismuthinidenes are reactive and … See more Transition metal-stabilized bismuthinidene The earliest examples of bismuthinidene complexes used transition metal chemistry to stabilize the Bi(I) center. These methods generally leveraged the ability of simple bismuth(I) See more As with other heavier carbene analogs, the structural and electronic properties of bismuthinidenes are in large part driven by the See more Theoretically, bismuthinidenes are both Lewis acidic and Lewis basic due to their empty and filled p-type orbitals, respectively.
