Abstract
The bond valence parameters (RD) for homoleptic SnⅡ)-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 8=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, R0=0.1956 nm with 6=0.037 nm can be used to assign the oxidation state of the central Sn(ll) ion for almost all coordination numbers. In contrast, the reported parameter set of R0=0.1859 nm with S=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.关键词
