Hello everybody,
in some previous works I used the Bond-Valence Parameter from Acta Cryst. (1991). B47, 192-197 by N. E. BRESE AND M. O'KEEFFE und did my calculations in Excel. I used that to assign O2- and F- in my compounds.
Now I have a crystal structure containing Yb(II) cations. The table in the work of BRESE and O'KEEFFE only give values between Yb(III) and F/O but nor for Yb(II).
Can somebody give me literature for Rij between Yb(II) and O/F?
If you additional to the Rij value know some software, which can calculate that, I also would be happy.
Best regards
