Hi, I want to draw a YBa2Cu3O7 cell. It is an ionic crystal (which is incidently superconducting at 90K). I know the structure (triple perovskite), but I don't know how big (relatively at least) the atoms should be in my drawing. Surely, it is known what the radii of each atom is in this compound. Where or how would I find the values?
