Materials Data on Ca6Sn2NO by Materials Project

Abstract

Ca6Sn2NO is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ca is bonded in a linear geometry to four equivalent Sn, one N, and one O atom. All Ca–Sn bond lengths are 3.45 Å. The Ca–N bond length is 2.42 Å. The Ca–O bond length is 2.46 Å. Sn is bonded to twelve equivalent Ca atoms to form SnCa12 cuboctahedra that share corners with twelve equivalent SnCa12 cuboctahedra, faces with six equivalent SnCa12 cuboctahedra, faces with four equivalent NCa6 octahedra, and faces with four equivalent OCa6 octahedra. N is bonded to six equivalent Ca atoms to form NCa6 octahedra that share corners with six equivalent OCa6 octahedra and faces with eight equivalent SnCa12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. O is bonded to six equivalent Ca atoms to form OCa6 octahedra that share corners with six equivalent NCa6 octahedra and faces with eight equivalent SnCa12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.
