The reaction of the stannylene R2Sn: (R = 2-tBu-4,5,6-Me3C6H) with R′2Sn (R′ = Si(SiMe3)3) proceeds with substituent exchange to afford the heteroleptic stannylene RR′Sn: which, in the solid state, forms the distannene RR′Sn = SnRR′ (7). The X-ray structure analysis of 7 reveals a trans-bent arrangement of the substituents with a large fold angle of 44.9° and an Sn-Sn double bond length of 279.14(4) pm.
