The weak central Si‐Si bond in 1 is surprisingly short (2.373 Å)—its length is almost the same as that of the SiSi bonds in trans,trans,trans ‐( t BuMeSi) 4 (2.377 Å). The Si1Si3 bond was expected to be particularly long owing to the high p‐character and in analogy to the bonding in bicyclobutanes.
