The bond valence parameters (R-0) for homoleptic Sn(II) X and Sn(IV) X complexes, where X=O, S, N, C, P, As, Se, Te, F, Cl, Br, and I, were determined using data retrieved from the Cambridge Structural Database with bond valence parameter B=0.037 nm. Some are the first reported experimental values for Sn(II)-X or Sn(IV)-X bonds. In the case of Sn(II)-O, R-0=0.1956 nm with B=0.037 nm can be used to assign the oxidation state of the central Sn(II) ion for almost all coordination numbers. In contrast, the reported parameter set of R-0=0.1859 nm with B=0.055 nm appears applicable mainly to complexes with a low coordination number. Our results suggest that further studies of bond valence parameters are required to better understand the factors that are important in bond valence sum (BVS) calculations.
