Materials Data on CsSmO2 by Materials Project
CsSmO2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Cs–O bond lengths are 3.12 Å. Sm3+ is bonded to six equivalent O2- atoms to form edge-sharing SmO6 octahedra. All Sm–O bond lengths are 2.41 Å. O2- is bonded to three equivalent Cs1+ and three equivalent Sm3+ atoms to form a mixture of distorted edge, corner, and face-sharing OCs3Sm3 octahedra. The corner-sharing octahedra tilt angles range from 0–40°.
