Bond-lengths for different Si-structures (Å)*. Note that for the Si=Si double bond lengths of disilenes vary between 2.14 and 2.29 Å and are nearly 5 to 10% shorter than the Si–Si single bond lengths of corresponding disilanes. This rate of bond shortening is less than 13% in carbon compounds [57].
