Hi, recently I synthesize a material containing C-O-Sn bond (For specification, Sn is connected to butyl group). I wonder if there is any technique to characterize this bond? Thank you in advance!
Dear Han Wang many thanks for asking this very interesting technical question. The answer to this question depends on what kind of "material containing C-O-Sn bond" you have. Is it a material in the sense of e.g. thin films and nanomaterials or is it a crystalline molecular compound? In the latter case you could try to grow single-crystals for a single-crystal X-ray diffraction study. This would certainly be the best way to unambiguously characterize the C–O–Sn bond in your material / compound. In all cases, however, IR spectroscopy would be a suitable characterization method. If possible, please have a look at the following relevant research article:
Article Darstellung von Trimethylzinn-methoxyd
In this work the authors synthesized and characterized the compound trimethyltin-methoxide, (CH3)3Sn–O–CH3. The most important finding with respect to your question is that in the IR spectrum the vibration of the C–O–Sn bond was found at 1035 cm–1. So it should be easy to check the IR spectrum of your material for a band in this region.
I hope this helps. Good luck with your research and best wishes, Frank Edelmann
Please use 119Sn NMR ( if solubility is not a problem), which is better among three NMR active Sn nuclei with all having I = 1/2. Also FT IR should help.
