Materials Data on TcSnO3 by Materials Project

Abstract

TcSnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tc2+ is bonded to six equivalent O2- atoms to form TcO6 octahedra that share corners with six equivalent TcO6 octahedra and faces with eight equivalent SnO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tc–O bond lengths are 1.99 Å. Sn4+ is bonded to twelve equivalent O2- atoms to form SnO12 cuboctahedra that share corners with twelve equivalent SnO12 cuboctahedra, faces with six equivalent SnO12 cuboctahedra, and faces with eight equivalent TcO6 octahedra. All Sn–O bond lengths are 2.82 Å. O2- is bonded in a linear geometry to two equivalent Tc2+ and four equivalent Sn4+ atoms.
