Aggregation of Hydrogen Bonded Dimeric Tri-Organotin Amino Substituted Pyrimidine-2-Thiolates

The synthesis of six tri-organotin compounds with 4-amino and 4,6-diaminopyrimidine-2-thiolate is described. The compounds have the general formula R3Sn(thiolate) where R = Me, Bu, or Ph. The compounds are investigated by a variety of spectroscopic techniques both in solution and in the solid state. The environment around the tin centres proves to be tetrahedral with monodentate thiolate anions as is inferred from the infrared and NMR spectra....
