Knowing that solids are formed by atoms, and that atoms have, indeed, a size, it is no wonder that the size of atoms does influence the Chemistry of Solids. However, the way the atoms size makes its influence can be rather elaborate, even surprising¡. In the present lecture, after a brief introduction of atoms and ions sizes, we will present two examples of the marked influence of Rare Earth (RE) ions sizes in two very interesting cuprate families:
* The High Pressure/High Temperature Solid State Synthesis of Materials of the so-called rutheno-cuprate family: RuSr2RECu2O8 (The unexpected influence of the f-electrons)
* The presence, or absence, of superconducting properties in the family of partly substituted copper in YSrCuO: i.e. Mo0.3Cu0.7Sr2RECuO7+d. (Anion & cation order/disorder)
* The third example shows the correlation of P & T in the ordering in the A & B positions of a quadruple perovskite “Sr2RECu2IrO9-”.[3]
