Materials Data on Li4H5Rh by Materials Project
Li4RhH5 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to five H atoms to form distorted LiH5 trigonal bipyramids that share corners with two equivalent RhH6 octahedra, corners with five LiH5 trigonal bipyramids, edges with two equivalent RhH6 octahedra, and edges with five LiH5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 29–48°. There are a spread of Li–H bond distances ranging from 1.90–2.14 Å. In the second Li site, Li is bonded to five H atoms to form LiH5 trigonal bipyramids that share corners with two equivalent RhH6 octahedra, corners with five LiH5 trigonal bipyramids, edges with two equivalent RhH6 octahedra, and edges with five LiH5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 37–56°. There are a spread of Li–H bond distances ranging from 1.94–2.11 Å. Rh is bonded to six H atoms to form RhH6 octahedra that share corners with two equivalent RhH6 octahedra, corners with eight LiH5 trigonal bipyramids, and edges with eight LiH5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 1°. There are a spread of Rh–H bond distances ranging from 1.75–1.95 Å. There are three inequivalent H sites. In the first H site, H is bonded to four Li and two equivalent Rh atoms to form distorted HLi4Rh2 octahedra that share corners with two equivalent HLi4Rh2 octahedra, corners with eight HLi4Rh trigonal bipyramids, and edges with eight HLi4Rh trigonal bipyramids. The corner-sharing octahedral tilt angles are 1°. In the second H site, H is bonded to four Li and one Rh atom to form distorted HLi4Rh trigonal bipyramids that share corners with two equivalent HLi4Rh2 octahedra, corners with five HLi4Rh trigonal bipyramids, edges with two equivalent HLi4Rh2 octahedra, and edges with five HLi4Rh trigonal bipyramids. The corner-sharing octahedra tilt angles range from 40–63°. In the third H site, H is bonded to four Li and one Rh atom to form HLi4Rh trigonal bipyramids that share corners with two equivalent HLi4Rh2 octahedra, corners with five HLi4Rh trigonal bipyramids, edges with two equivalent HLi4Rh2 octahedra, and edges with five HLi4Rh trigonal bipyramids. The corner-sharing octahedra tilt angles range from 31–56°.
