LiBeF4NH2NH3 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional and consists of four ammonia molecules, four ammonia molecules, and one LiBeF4 framework. In the LiBeF4 framework, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with four equivalent BeF4 tetrahedra. There are a spread of Li–F bond distances ranging from 1.86–1.91 Å. Be2+ is bonded to four F1- atoms to form BeF4 tetrahedra that share corners with four equivalent LiF4 tetrahedra. There are a spread of Be–F bond distances ranging from 1.55–1.59 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Be2+ atom. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to one Li1+ and one Be2+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to one Li1+ and one Be2+ atom. In the fourth F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Be2+ atom.
