I am trying to identify a tin-compound from the reaction below (for a biologist friend), but I do not have much experience in inorganic synthesis and I can't find an answer on Sci-Finder.

Reaction: Under air atmosphere, heat a 20mM solution of SnCl2 in acetic acid (3%) and isopropanol (97%) for 20 hours.

Does anybody know what type of tin species this reaction generates?  Would this make a tin-cluster type of compound or something like Sn(OAc)2?  Would it make multiple products?  Any help or guidance is appreciated!

I don't know about a substitution product. But Sn(II) is good reducing agent. Maybe the acid gets reduced to the alcohol? Or aldehyde? I'm not really sure. This is what I feel could happen. Just another possibility.
