Materials Data on Zr2CoH5 by Materials Project
Zr2CoH5 crystallizes in the tetragonal P4/ncc space group. The structure is three-dimensional. Zr2+ is bonded in a 8-coordinate geometry to eight H1- atoms. There are a spread of Zr–H bond distances ranging from 2.07–2.16 Å. Co1+ is bonded in a square co-planar geometry to four equivalent H1- atoms. All Co–H bond lengths are 1.63 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded to four equivalent Zr2+ atoms to form a mixture of edge and corner-sharing HZr4 tetrahedra. In the second H1- site, H1- is bonded to three equivalent Zr2+ and one Co1+ atom to form a mixture of edge and corner-sharing HZr3Co tetrahedra.
