Materials Data on Cs2YbH4 by Materials Project
Cs2YbH4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine H1- atoms. There are a spread of Cs–H bond distances ranging from 3.13–3.27 Å. Yb2+ is bonded to six H1- atoms to form corner-sharing YbH6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.31 Å) and two longer (2.33 Å) Yb–H bond lengths. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Yb2+ atoms. In the second H1- site, H1- is bonded to five equivalent Cs1+ and one Yb2+ atom to form a mixture of distorted corner and edge-sharing HCs5Yb octahedra. The corner-sharing octahedra tilt angles range from 0–2°.
