The reactions of SnX 4 (X = Cl, Br) with benzofuroxan and some substituted derivatives are studied, and the hexacoordinated complexes SnCl 4 (Y‐C 6 H 3 N 2 O 2 ) 2 (Y = H, Cl, Me, OMe), and SnBr 4 (Y‐C 6 H 3 N 2 O 2 ) 2 (Y = H, OMe) have been isolated. The adducts are studied by IR, Raman, and 119 Sn Mössbauer spectroscopies, which suggest a cis structure (C 2v symmetry) for them. The good correlation between υ SnCl (IR and Raman spectra) and the Mössbauer quadrupole splitting for the SnCl 4 complexes, supports the consistency of the structural assignments. The Mössbauer spectra show resolved quadrupole doublets, in spite of the cis structure of the adducts, which emphasizes the fact that the resolvable or unresolvable nature of the doublets cannot be used confidently to elucidate the structure of tin tetrahalide complexes.
