Materials Data on Li2(BH)11 by Materials Project

(Li(BH)3)2(BH)5 crystallizes in the monoclinic C2 space group. The structure is one-dimensional and consists of ten boranediylradical molecules and two Li(BH)3 ribbons oriented in the (1, 0, 0) direction. In each Li(BH)3 ribbon, there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted see-saw-like geometry to four H+0.64+ atoms. There is two shorter (1.88 Å) and two longer (2.11 Å) Li–H bond length. In the second Li1+ site, Li1+ is bonded in a distorted see-saw-like geometry to four H+0.64+ atoms. There is two shorter (1.88 Å) and two longer (2.11 Å) Li–H bond length. There are three inequivalent B+0.82- sites. In the first B+0.82- site, B+0.82- is bonded in a distorted single-bond geometry to one H+0.64+ atom. The B–H bond length is 1.21 Å. In the second B+0.82- site, B+0.82- is bonded in a distorted single-bond geometry to one H+0.64+ atom. The B–H bond length is 1.21 Å. In the third B+0.82- site, B+0.82- is bonded in a distorted single-bond geometry to one H+0.64+ atom. The B–H bond length is 1.21 Å. There are three inequivalent H+0.64+ sites. In the first H+0.64+ site, H+0.64+ is bonded in a T-shaped geometry to two Li1+ and one B+0.82- atom. In the second H+0.64+ site, H+0.64+ is bonded in a water-like geometry to one Li1+ and one B+0.82- atom. In the third H+0.64+ site, H+0.64+ is bonded in a water-like geometry to one Li1+ and one B+0.82- atom.
