Materials Data on InBr3 by Materials Project

InBr3 is Aluminum trichloride structured and crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one InBr3 sheet oriented in the (0, 0, 1) direction. In3+ is bonded to six Br1- atoms to form edge-sharing InBr6 octahedra. All In–Br bond lengths are 2.73 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in an L-shaped geometry to two equivalent In3+ atoms. In the second Br1- site, Br1- is bonded in an L-shaped geometry to two equivalent In3+ atoms.

Materials Data on Th(InBr3)2 by Materials Project

Th(InBr3)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two Th(InBr3)2 ribbons oriented in the (0, 0, 1) direction. Th4+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Th–Br bond distances ranging from 2.90–3.15 Å. In1+ is bonded in a 1-coordinate geometry to three Br1- atoms. There are a spread of In–Br bond distances ranging from 3.39–3.50 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Th4+ atom. In the second Br1- site, Br1- is bonded in a distorted water-like geometry to two equivalent Th4+ and one In1+ atom. In the third Br1- site, Br1- is bonded in a 1-coordinate geometry to one Th4+ and two equivalent In1+ atoms.

Preparation and Single-Crystal X-Ray Structures of Four Related Mixed-Ligand 4-Methylpyridine Indium Halide Complexes

We describe the structures of four related indium complexes obtained during synthesis of solid-state materials precursors. Indium adducts of halides and 4-methylpyridine, InX3(pic)3 (X = Cl, Br; pic = 4-methylpyridine) consist of octahedral molecules with meridional (mer) geometry. Crystals of mer-InCl3(pic)3 (1) are triclinic, space group P1(bar) (No. 2), with a = 9.3240(3), b = 13.9580(6), c = 16.7268 (7) A, alpha = 84.323(2), beta = 80.938(2), gamma = 78.274(3)Z = 4, R = 0.035 for 8820 unique reflections. Crystals of mer-InBr3(pic)3 (2) are monoclinic, space group P21/n (No. 14), with a = 15.010(2), b = 19.938(2), c = 16.593(3), beta = 116.44(1)Z = 8, R = 0.053 for 4174 unique reflections. The synthesis and structures of related compounds with phenylsulfide (chloride) (3) and a dimeric complex with bridging hydroxide (bromide) (4) coordination is also described. Crystals of trans-In(SC6H5)Cl2(pic)3 (3) are monoclinic, space group P21/n (No. 14), with a = 9.5265(2), b = 17.8729(6), c = 13.8296(4), beta = 99.7640(15)Z = 4, R = 0.048 for 5511 unique reflections. Crystals of [In(mu-OH)Br2(pic)22 (4) are tetragonal, space group = I41cd (No. 110) with a = 19.8560(4), b = 19.8560(4), c = 25.9528(6), Z = 8, R = 0.039 for 5982 unique reflections.
