Abstract

(LiH4(NO3)2)2N2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four ammonia molecules and four LiH4(NO3)2 clusters. In each LiH4(NO3)2 cluster, Li1+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.97 Å) and two longer (2.06 Å) Li–O bond lengths. N+2.33+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.26 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one N+2.33+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom.
