inorder to solve the structural details of my solid solution I have to know the ionic size of V4+ ions having co ordination number 4. Please anybody can help me to solve this issue.
I am not a specialist of the liquids but I think that you will take benefit to read
my paper “Atoms and Cristal structures” that you will find on my ResearchGate Ann. Chim. Sci. Mat., 2009, 33, (6), pp435-68. In section 5.2 I discuss the crystal and the valence. In particular I use the role of the Krypton or Xenon shell in the coordination problem. I have introduce this hypothesis in the paper “On the phase transformation of Ce gamma and Ce alpha" that you will also find on my ResearchGate.
