The analysis of organotin compounds from the natural environment,n the electroplating of steel . Early records indicate that tin has been in use for 5000 years, its use in an alloy with copper to form bronze was the basis of early civilization in the Western world. Compounds of tin have been used in dye preparations from Egyptian times; the first recorded or

The inorganic chemistry of tin,, formally, only the .-electrons are used leaving a non-bonding electron pair. Many compounds in both oxidation states are known. The +4 oxidation state is the more stable state and tin(II) compounds are moderately strong reducing agents .
