Thanks a lot four your help Chris. I found late at night the CIF card for Cr(CO)6, which has exactly the same structure and has similar lattice parameters. Kind regards, Ismael. > Ismael, > > You do really not need exact parameters which can is helpful in EXAFS. > Can > you find any reference

Ismael, You do really not need exact parameters which can is helpful in EXAFS. Can you find any references on the V-C bond length? Since CO is linear, the V-O and V-C-O scattering should be possible to roughly establish. I think a number of general inorganic textbooks might have information suc

Dear XAS fellows: I have to fit EXAFS data of a nanoparticle colloidal suspension. TEM and NMR data indicate that I have nanoparticles of V(CO)_6 (vanadium hexacarbonyl). The system is orthorhombic, space group Pnma (Nr. 62), and I know the nominal values for the lattice parameters. However, I nee
