Abstract

Halogen exchange reactions between hexacoordinate tin dihalides (LⁿCH₂)₂SnX₂ and (LⁿCH₂)₂SnY₂ (LⁿCH₂ = C,O-chelate n-membered lactamomethyl ligand, n = 5–7, X, Y = Cl, Br, I) produce mixed dihalides (LⁿCH₂)₂SnXY. Along with the signals of original complexes, NMR ¹¹⁹Sn spectra of solutions containing two different homodihalides show the third signal with a median chemical shift. The results of NMR monitoring studies, conductivity data and quantum-chemical calculations suggest that mixed dihalides readily form in solutions, although these complexes have not been isolated as individual compounds.
