Title: Materials Data on K3MnH5 by Materials Project

Abstract

K3MnH5 is Pb(Zr_(1-x)Ti_x)O3-like structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to four H1- atoms. There are two shorter (2.73 Å) and two longer (2.79 Å) K–H bond lengths. In the second K1+ site, K1+ is bonded in a linear geometry to two equivalent H1- atoms. Both K–H bond lengths are 2.91 Å. Mn2+ is bonded in a tetrahedral geometry to four equivalent H1- atoms. All Mn–H bond lengths are 1.75 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded in a 2-coordinate geometry to one K1+ and one Mn2+ atom. In the second H1- site, H1- is bonded to six K1+ atoms to form corner-sharing HK6 octahedra. The corner-sharing octahedra tilt angles range from 0–29°.
