A series of reactions between various organotin compounds and iron carbonyls has been investigated. By refluxing mixtures of organotin halides and pentacarbonyl iron, several complexes with tin–iron bonds have been obtained. Among the types of compound isolated are those of formula [R2SnFe(CO)4]2, [R2SnCl]2Fe(CO)4, R4Sn3[Fe(CO)4]4, and Sn[Fe(CO)4]4. The last compound, tetrakis(tetracarbonyliron)tin, can also be synthesised by reaction of hexabutylditin with pentacarbonyliron, but more successfully by treating stannic chloride with the anion Fe(CO)4–2. Compounds of formula type (R3Sn)2Fe(CO)4 and [R2SnFe(CO)4]2 can be prepared by refluxing pentacarbonyliron with trialkyltin hydrides and dialkyltin dihydrides, respectively. A number of properties of the new compounds are reported, including their infrared spectra in the carbonyl stretching region.
