Materials Data on SrCdO2 by Materials Project
SrCdO2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sr2+ is bonded to six O2- atoms to form SrO6 octahedra that share corners with six equivalent SrO6 octahedra, edges with four equivalent SrO6 octahedra, and edges with eight equivalent CdO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.48 Å) and four longer (2.51 Å) Sr–O bond lengths. Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with six equivalent CdO6 octahedra, edges with four equivalent CdO6 octahedra, and edges with eight equivalent SrO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.48 Å) and four longer (2.51 Å) Cd–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Cd2+ atoms to form a mixture of edge and corner-sharing OSr4Cd2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to two equivalent Sr2+ and four equivalent Cd2+ atoms to form OSr2Cd4 octahedra that share corners with six equivalent OSr2Cd4 octahedra and edges with twelve OSr4Cd2 octahedra. The corner-sharing octahedral tilt angles are 0°.
