Re. Allan et al., FACILE SYNTHESIS OF SN4N4 CUBANES - SYNTHESES AND STRUCTURES OF [SN(NC6H11)](4) AND [SN(2-NCH2C5H4N)](4), Journal of the Chemical Society. Dalton transactions, (12), 1995, pp. 1991-1994
The low-temperature reaction of Sn(NMe(2))(2) with primary amines (NH(
2)R) (1:1 equivalents) is a general route by which imido tin(II) cuban
es [Sn(NR)](4) can be prepared. It has been exemplified by the direct
reactions of the relatively non-acidic primary amines NH2(C6H11) and 2
-H2NCH2C5H4N, producing the cubanes [Sn(NC6H11)](4) 1 and [Sn(2-NCH2C5
H4N)](4) 2. The structures of both complexes have been established by
X-ray crystallography.
