Abstract
Based on the latest available crystal data and the reported bond valence parameters, the linear correlation between the bond valence parameter R0 with B = 0.37 Å for M—O bonds (M = V, Fe and Cu) and the metal oxidation state n is shown for the first time. For V—O bonds, a linear equation of R0 ∼ n is perfectly established as R0 = 0.0250n + 1.674 (n = 2–5). Similarly, a linear equation for Fe—O bonds is fitted as R0 = 0.0335n + 1.648 (n = 2–4), as well as R0 = 0.0855n + 1.482 (n = 1–3) for Cu—O bonds fitted properly. In addition, the linear correlation between R0 and n within certain range of B values for V—O and Fe—O bonds is also established. Consequently, the oxidation-state independent parameters (R0, B) of (1.788, 0.32 Å) for V—O bonds and (1.795, 0.30 Å) for Fe—O bonds can be derived from the zero slope of the R0 ∼ n straight lines. However, a similar parameter pair for Cu—O bonds cannot be found using this unique approach.
