Tris(N,N-dimethylanilinium) tri-[mu]-bromido-bis[tribromidoantimonate(III)]

Abstract top

In the title compound, (C8H12N)3[Sb2Br9], two of the three unique N,N-dimethyanilinium cations exhibit flip-flop disorder with an occupancy ratio of 0.58 (1):0.42 (1). N-H...Br hydrogen bonds link the organic cations and bioctahedral face-sharing anions into a three-dimensional network.

Comment top

This study is a part of our investigations on the syntheses, structures and phase transitions of halogenoantimonate (III) anions in combination with organic cations (Bujak & Angel, 2005; Chaabouni et al., 1997; Chaabouni et al., 1998; Chaabouni & Kamoun, 1998). In these compounds the Sb atom shows a tendency toward distorted octahedral coordination with some rather long Sb—X bonds, which is attributed to the aspherical distribution of the lone pair electrons at Sb(III). The asymmetric unit of the title compound, consists of one isolated [Sb2Br9]3- anion with one ordered and two disordered N,N-dimethylanilinium cations which exhibit flip-flop disorder with 0.58 (1):0.42 (1) occupancy ratio. The inorganic ions are built up from two distorted [SbBr6]3- octahedra sharing one face. Two types of Sb—Br distances are present within the Sb2Br9 group: six short Sb—Br (terminal) distances [2.5696 (7)–2.6925 (6) Å)] and three longer Sb—Br (bridging) distances [(2.9558 (7)–3.2393 (7) Å)]. The interatomic Br—Sb—Br angles involving the terminal Br atoms are greater than the ideal 90°, whereas those between the bridging ones are less than 90°. The average Sb—Br—Sb angle is 89.92 (2)°. According to the valence-shell electron-pair repulsion (VSEPR) model, the lone pair electrons on Sb(III) atom may be considered as stereochemical non active. The phenyl rings of the N,N-dimethylanilinium cations are practically planar with the greatest deviation from the six-atoms least squares plane being 0.0088 Å, 0.0383 Å,0.0518 Å, 0.0605 Å and 0.0970 Å respectively. The π-π interactions between phenyl rings may be neglected (> 4 Å); in fact the shortest distances between the centroids of the rings are: Cg(1)···Cg(1)i = 5.521 (4) Å,Cg(2)···Cg(2)ii = 4.227 (15) Å, Cg(2)···Cg(3)ii = 4.214 (19) Å and Cg(3)···Cg(3)ii = 4.26 (2) Å [Cg(1), Cg(2) and Cg(3) are the centroids of the C1···C6, C9···C14 and C17···C22 rings respectively; symmetry codes: (i) 1 - x, -y, -z; (ii) -x, 1 - y, 1 - z]. The major contributions to the cohesion and the stability of the structure is the presence of N—H···Br hydrogen bonds which provide a linkage between N,N-dimethylanilinium cations and [Sb2Br9]3- anions which include five relatively medium contacts, with H···Br and N..Br distances ranging from 2.40 Å to 2.68 Å and 3.23 (3) Å to 3.48 (3) Å, respectively (Fig. 2 and Table 1).

Experimental top

Crystals of (C8H12N)3[Sb2Br9] were obtained by dissolving antimony (III) oxide Sb2O3 and N,N-dimethylanilinium bromide C8H12NBr (molar ratio 3:1) in 50 ml of a solution of HBr (24%). After a slow solvent evaporation prismatic yellow crystals suitable for X-ray analysis were obtained. They were washed with diethyl ether and dried over P2O5.

Refinement top

The positions of the two disordered N,N-dimethylanilinium cations were initially refined with different occupancy ratios, but the refinement converged extremely slowly when using anisotropic atomic displacement parameters. Since the refined occupancy factors for the two cations were nearly equal upon refining with isotropic atomic displacement parameters it was decided to use a single occupancy factor for the final anisotropic refinement. SADI and EADP restraints were used. All H atoms were geometrically positioned and treated as riding on their parent atoms, with C—H = 0.93 Å for the phenyl, 0.96 Å for the methyl and N—H = 0.91 Å with Uiso(H) = 1.2 Ueq(C-phenyl, N) or 1.5 Ueq(C-methyl).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
