Materials Data on K3AlH6 by Materials Project

Kristin Persson
K3AlH6 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to eight H1- atoms to form distorted KH8 hexagonal bipyramids that share corners with four equivalent KH8 hexagonal bipyramids, edges with six equivalent KH8 hexagonal bipyramids, and edges with four equivalent AlH6 octahedra. There are four shorter (2.60 Å) and four longer (2.95 Å) K–H bond lengths. In the...
