BeH8(NO5)2 crystallizes in the tetragonal I-42d space group. Be(1) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. N(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one N(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one N(1) and one H(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Be(1), one H(1), and one H(2) atom.
