119Sn Mossbauer spectroscopy

Polymeric trigonal bypiramidal Sn structure 221 with trans O—Sn—O binding. Also variable-temperature 119Sn Mossbauer spectroscopy (see compound 50 in Table 5). These compounds are important pesticides. 

In contrast to the above systems, where electronic support interactions were negligible, the work of Bowles and Cranshaw 198) points to the presence of such effects for tin on platinum. Tin was deposited on platinum electrodes at a potential high enough to ensure a fractional tin monolayer. Subsequent 119Sn Mossbauer spectroscopy showed a tin isomer shift characteristic of a Pt-Sn alloy, thereby evidencing the electronic interaction between these two metals. The possible modification by the support of the... 

Sn Mossbauer spectroscopy has been used to a limited extent to characterize some of the tin complexes described herein. A table of isomer shifts is provided here, but it is clear that much more data are required before any trends might emerge. 

Organotin(IV) compounds are Lewis acids. The crystalline structure of Lewis acid-base adducts between compounds R SnCl4- (/ = 0,..., 3) and Ni complexes with Schiff bases was determined by XRD, 119Sn Mossbauer and IR spectroscopy. Adducts are formed in 1 1, 1 2 and 2 1 ratios121.
