Materials Data on LiB(H4N)2 by Materials Project
LiB(NH4)2 crystallizes in the monoclinic Cc space group. The structure is one-dimensional and consists of two LiB(NH4)2 ribbons oriented in the (-1, 1, 0) direction. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 6-coordinate geometry to two N3- and four H1+ atoms. There are one shorter (2.10 Å) and one longer (2.13 Å) Li–N bond lengths. There are a spread of Li–H bond distances ranging from 1.96–2.14 Å. In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to two N3- and four H1+ atoms. There are one shorter (2.11 Å) and one longer (2.12 Å) Li–N bond lengths. There are a spread of Li–H bond distances ranging from 1.92–2.12 Å. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a tetrahedral geometry to four H1+ atoms. All B–H bond lengths are 1.23 Å. In the second B3- site, B3- is bonded in a tetrahedral geometry to four H1+ atoms. There is one shorter (1.22 Å) and three longer (1.23 Å) B–H bond length. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted water-like geometry to one Li1+ and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a distorted water-like geometry to one Li1+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. In the third N3- site, N3- is bonded in a distorted water-like geometry to one Li1+ and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the fourth N3- site, N3- is bonded in a distorted water-like geometry to one Li1+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. There are sixteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one B3- atom. In the second H1+ site, H1+ is bonded in a water-like geometry to one Li1+ and one B3- atom. In the third H1+ site, H1+ is bonded in a water-like geometry to one Li1+ and one B3- atom. In the fourth H1+ site, H1+ is bonded in a 3-coordinate geometry to two Li1+ and one B3- atom. In the fifth H1+ site, H1+ is bonded in a 3-coordinate geometry to two Li1+ and one B3- atom. In the sixth H1+ site, H1+ is bonded in a water-like geometry to one Li1+ and one B3- atom. In the seventh H1+ site, H1+ is bonded in a water-like geometry to one Li1+ and one B3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one B3- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the thirteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.
