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.
