Materials Data on AgB11H6CBr6 by Materials Project
Ag(BBr)5B5CH6BBr crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of four bromoborane molecules; four B5CH6 clusters; and two Ag(BBr)5 ribbons oriented in the (1, 0, 0) direction. In each B5CH6 cluster, there are three inequivalent B+0.27+ sites. In the first B+0.27+ site, B+0.27+ is bonded in a bent 120 degrees geometry to one C4- and one H1+ atom. The B–C bond length is 1.70 Å. The B–H bond length is 1.19 Å. In the second B+0.27+ site, B+0.27+ is bonded in a bent 120 degrees geometry to one C4- and one H1+ atom. The B–C bond length is 1.70 Å. The B–H bond length is 1.19 Å. In the third B+0.27+ site, B+0.27+ is bonded in a bent 120 degrees geometry to one C4- and one H1+ atom. The B–C bond length is 1.70 Å. The B–H bond length is 1.19 Å. C4- is bonded in a 1-coordinate geometry to five B+0.27+ and one H1+ atom. The C–H bond length is 1.08 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one B+0.27+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one B+0.27+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one B+0.27+ atom. In each Ag(BBr)5 ribbon, Ag1+ is bonded to six Br1- atoms to form corner-sharing AgBr6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are a spread of Ag–Br bond distances ranging from 2.83–3.02 Å. There are three inequivalent B+0.27+ sites. In the first B+0.27+ site, B+0.27+ is bonded in a single-bond geometry to one Br1- atom. The B–Br bond length is 1.98 Å. In the second B+0.27+ site, B+0.27+ is bonded in a single-bond geometry to one Br1- atom. The B–Br bond length is 1.97 Å. In the third B+0.27+ site, B+0.27+ is bonded in a single-bond geometry to one Br1- atom. The B–Br bond length is 1.98 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to two equivalent Ag1+ and one B+0.27+ atom. In the second Br1- site, Br1- is bonded in a distorted L-shaped geometry to one Ag1+ and one B+0.27+ atom. In the third Br1- site, Br1- is bonded in a distorted L-shaped geometry to one Ag1+ and one B+0.27+ atom.
