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
