Materials Data on BeH8(NO5)2 by Materials Project
BeH8(NO5)2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Be2+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Be–O bond lengths are 1.62 Å. N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.28 Å) N–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.67 Å) H–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one N5+ and one H1+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Be2+ and two H1+ atoms.
