                                    The reaction of the stannylene R2Sn: (R = 2-tBu4,5,6-Me3C6H) with R'Sn-2 (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 degrees and an Sn-Sn double bond length of 279.14(4) pm.
