We report on the synthesis of a distannyne supported by a pincer ligand bearing pendant amine donors that is capable of reversibly activating E-H bonds at one or both of the tin centres through dissociation of the hemi-labile N-Sn donor/acceptor interactions. This chemistry can be exploited to sequentially (and reversibly) assemble mixed-valence chains of tin atoms of the type ArSn{Sn(Ar)H}nSnAr (n=1, 2). The experimentally observed (decreasing) propensity towards chain growth with increasing chain length can be rationalized both thermodynamically and kinetically by the electron- withdrawing properties of the -Sn(Ar)H- backbone units generated via oxidative addition.

- 10Lithiation of 2,6(iPr2NCH2)2C6H3Br followed by reaction with SnCl2 gives a crystalline material formulated as ArNiPr2SnCl0.6Br0.4 (based on 119Sn NMR data), which can be used for further reaction chemistry. ArNiPr2SnBr can be prepared selectively by using SnBr2 instead of SnCl2, and ArNiPr2SnI then synthesized from the bromide via reaction with Me3SiI (see ESI for synthetic details).

- 25Cooling such a solution comprised of equimolar quantities of 2/4 to ca. 190 K does lead to the appearance of additional signals in the 1H NMR spectrum of the mixture, although given the broadness of the spectrum it is difficult to ascertain whether these arise from the formation of 5 at low temperatures, or from the slowing of fluxional processes associated with 2/4. Low temperature 119Sn NMR is also hampered by significant signal broadening below 243 K.
