Abstract

The coordination structure of V^IV ions in the mixed-solvent systems of HCONH₂ and HCO₂NH₄ has been investigated using EXAFS (extended X-ray absorption fine structure) method for the V K-edge. V^IV ions exist as vanadyl ions (VO²⁺) and form distorted [VO(HCO₂)_x(HCONH₂)_5-x] ^2-x(2 ≤ x ≤ 5) octahedra with one short V - O bond length of ca. 1.63 Å and five V-O bond length of ca. 2.07 Å in the HCONH₂-HCO₂NH₄ system.
