Abstract:
One-electron oxidation of the 1,2,4-diazaphospholide anion [3,5-R2dp](-) by BiCl3 generated several remarkable paddlewheel dibismuthanes [L2(Bi-Bi)L2] (L = η(1),η(1)-3,5-R2dp, R = tBu, iPr, or Ph) with very short Bi-Bi single bond lengths (2.7964(4)-2.8873(3) Å).

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...
