A new quaternary oxide, calcium yttrium stannate, Ca0.8Y 2.4Sn0.8O6, is isostructural with Mg 3TeO6 (trigonal, R3̄). The empirical formula can be expressed as (Ca0.2667Y0.7333)6(Y 0.4Sn0.6)SnO12. The Ca/Y site has a distorted coordination octahedron of O atoms, with Ca/Y-O distances ranging from 2.227 (3) to 2.350 (3) Å, while the octahedra of O atoms that coordinate to the Sn and Y/Sn sites are nearly regular, with an Sn-O distance of 2.066 (2) Å and a Y/Sn-O distance of 2.147 (3) Å.
