Ca(0.8)Y(2.4)Sn(0.8)O(6), a quaternary oxide with mixed occupations of Ca/Y and Y/Sn.
A new quaternary oxide, calcium yttrium stannate, Ca(0.8)Y(2.4)Sn(0.8)O(6), is isostructural with Mg(3)TeO(6) (trigonal, R-3). The empirical formula can be expressed as (Ca(0.2667)Y(0.7333))(6)(Y(0.4)Sn(0.6))SnO(12). 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) Angstrom, 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) Angstrom and a Y/Sn-O distance of 2.147 (3) Angstrom.
