Abstract

Powder neutron diffraction is used to solve the structures of the n=2 and n=∞ members of the Ruddlesden-Popper series, Sr(n+1)Sn(n)O(3n+1). It is confirmed that SrSnO3 adopts the GdFeO3 structure space group Pbnm. It is found that Sr3Sn2O7 adopts a C-centered orthorhombic structure (space group Cmcm). A comparison is made between the cooperative tilting of the SnO6 octahedra as a function of the number of adjoining Sn-O planes. It is shown that the inclusion of the rock salt layer within the structure greatly relieves the internal strain caused by the mismatch between the SnO2 and Sr2O2 layers.
