Bond Valence Parameter for Yb(II)?

26 January 2023 1 9K Report

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
