(2,6-Mes2H3C6)2BiH, a Stable, Molecular Hydride of a Main Group Element of the Sixth Period, and Its Conversion to the Dibismuthene (2,6-Mes2H3C6)BiBi(2,6-Mes2C6H3)

The first stable organic hydride of a main group element of the sixth period (1) has been prepared by the simple reduction of the corresponding chloride precursor. Interestingly, compound 1 transforms into the dibismuthene 2 when heated Eq. (1).
