根据键价理论中的指数方程sij=exp[(Ro-rij)/B],利用晶体结构报告中不同氧化态n的329个W-O键长数据,选取不同的B值对键价参数R0进行了拟合,建立了一系列R0-n线性方程,并进而得到与W氧化态无关的键价参数R0=0.1896 nm和B=0.028nm.与文献数据比较,本文拟合的键价参数取得了较好的键价和计算结果,讨论了几个应用的实例.

关键词: 键价参数, W—O键, 氧化态, 键价和

Based on the equation sij=exp[(R0-rij)/B] of bond valence approach and 329 W—O bond length data in literature, linear equations of bond valence parameter R0 with oxidation state n in different B for W—O bonds were established. The new bond valence parameters R0=0.1896 nm and B=0.028 nm independent of n were also derived. The parameters fitted in this work were proved to be more suitable for the bond valence calculations. Applications of these parameters to some examples were illustrated.

Key words: bond valence parameter, W—O bond, oxidation state, bond valence sum
