Abstract

Tin(II) methoxide reacts with N,N′‐dimethylaminoethanol (dmaeH) to yield Sn(dmae)~2~ (1) along with small amounts of the hydrolysis product Sn~6~(O)~4~(dmae)~4~ (2). The geometrically more regular iso‐structural cage Sn~6~(O)~4~(OEt)~4~ (3) was obtained as the only tractable product isolated from reaction of 2 and Sb(OEt)~3~, while 1 reacted with CdX~2~ (X = acac, I) to afford Sn(dmae)~2~Cd(acac)~2~ (4) and Sn(dmae)~2~CdI~2~ (5). The X‐ray structures of 2, 3 and 4 are reported. Decomposition of 4 under aerosol‐assisted chemical vapour deposition conditions leads to amorphous tin oxide films with no detectable cadmium (i.e. ca < 2% cadmium), rather than a stoichiometric Sn:Cd oxide.
