| Abstract: | 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. |
