Materials Data on AlB6H6(CCl3)2 by Materials Project
AlB2H6(CCl)2(BCl)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of sixteen chloroborane molecules and four AlB2H6(CCl)2 clusters. In each AlB2H6(CCl)2 cluster, Al3+ is bonded in a distorted trigonal pyramidal geometry to two C+3.50- and two Cl1- atoms. Both Al–C bond lengths are 1.95 Å. There are one shorter (2.47 Å) and one longer (2.52 Å) Al–Cl bond lengths. There are two inequivalent B1+ sites. In the first B1+ site, B1+ is bonded in a single-bond geometry to one Cl1- atom. The B–Cl bond length is 1.83 Å. In the second B1+ site, B1+ is bonded in a single-bond geometry to one Cl1- atom. The B–Cl bond length is 1.83 Å. There are two inequivalent C+3.50- sites. In the first C+3.50- site, C+3.50- is bonded to one Al3+ and three H+0.67+ atoms to form corner-sharing CAlH3 tetrahedra. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. In the second C+3.50- site, C+3.50- is bonded to one Al3+ and three H+0.67+ atoms to form corner-sharing CAlH3 tetrahedra. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. There are six inequivalent H+0.67+ sites. In the first H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. In the second H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. In the third H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. In the fourth H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. In the fifth H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. In the sixth H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one C+3.50- atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a water-like geometry to one Al3+ and one B1+ atom. In the second Cl1- site, Cl1- is bonded in a water-like geometry to one Al3+ and one B1+ atom.
