Source of material

Tetraphenyltin (0.85 g, 2 mmol) and 4-(dimethylamino)pyridine hydrobromide perbromide (Sigma-Aldrich; 0.72 g, 2 mmol) were dissolved in ethanol (50 mL). The resulting mixture was stirred at room temperature until a colourless solution was obtained. Next, triphenylarsine oxide (Sigma Aldrich; 0.64 g, 2 mmol) in ethanol (10 mL) was added to the mixture which was then refluxed for 3 h. After filtration, the filtrate was evaporated slowly until colourless crystals formed. The crystals were filtered, washed with a minimum amount of hexane and air-dried. Yield: 0.88 g (59.1%). M.pt (Mel-temp II digital melting point apparatus): 447–449 K. IR (Bruker Vertex 70v FTIR Spectrophotometer; cm−1): 1085 (m) ν(C—C), 997 (m) ν(As—O), 476 (w) ν(Sn—O). 1H NMR (Bruker Ascend 400 MHz NMR spectrometer, chemical shifts relative to Me4Si, CDCl3 solution at 40 °C; ppm): δ 7.47–7.66 (m, 30H, Phenyl-H). 13C{1H} NMR (as for 1H NMR): δ 128.0, 129.3, 131.5, 131.9, 132.5, 136.4 (Phenyl—C).

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.95 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).

Comment

Recently, the X-ray crystal structure determinations of two new triorganoarsine oxide adduct of organotin species were described, namely six-coordinate, trans-(4-MeC6H4CH2)2SnCl2(O=AsPh3)2 [5] and five-coordinate (4-MeC6H4CH2)3SnCl(O=AsPh3) [6]. The rest of the known, comparatively rare mononuclear species are also five-coordinate, that is, (4-ClC6H4CH2)3SnCl(O=AsPh3) [7], Ph3SnCl(O=AsPh3) [8] and (4-ClC6H4)3SnCl(O=AsPh3) [8]. In continuation of previous structural studies in this area [5], [6], [8], the crystal and molecular structures of the title triphenylarsine oxide adduct of tri(4-methylbenzyl)tin bromide, Ph3SnBr(O=AsPh3), (I), are described.

The molecular structure of (I) is shown in the figure (70% displacement ellipsoids) and features a distorted trigonal bipyramidal geometry with the three phenyl rings occupying equatorial positions, and with the bromido [Sn—Br1 = 2.6983(2) Å] and As-oxido [Sn—O1 = 2.2493(13) Å] atoms occupying axial positions; Br1—Sn—O1 = 177.18(3)°. The Sn atom lies 0.119(1) Å out of the trigonal plane in the direction of the Br1 atom. The Sn—C bond lengths span an experimentally distinct range, that is, from short Sn—C1 = 2.1326(19), Sn—C7 = 2.147(2) to longer Sn—C13 = 2.1514(19) Å. Similarly, there is a disparity in the C—Sn—C angles with the widest angles of C1—Sn—C7 = 120.16(7)° and C1—Sn—C13 = 124.06(7)° involving the C1-phenyl ring which forms the smallest dihedral angle with the C3 plane, that is, 21.95(7)° and the shortest Sn—C1 bond. The comparable dihedral angles for the C7- and C13-phenyl rings are 57.64(5) and 79.388(7)°, respectively, with the greater dihedral angle correlating with the longest Sn—C13 bond. When the molecule of (I) is viewed down the Sn⋯As axis, the phenyl rings bound to the Sn and As atoms are close to being staggered. The Sn—O1—As angle is bent, presenting an angle of 136.77(7)°. The C3O donor set around the As atom is based on a tetrahedron with the range of angles subtended at the As atom being a narrow 106.45(8)° for O1—As—C31 to a wide 115.55(7)° for O1—As—C19, indicating relatively minor distortions from the ideal geometry.

The most closely related literature precedent to (I) is the chlorido analogue, Ph3SnCl(O=AsPh3), (II) [8]; the structures are not isostructural. As would be expected, very similar coordination geometries are noted. The Cl1—Sn—O1 angles in (II) are 139.3(2) and 139.4(2)° for the two independent molecules comprising the asymmetric unit and are over two degrees wider compared with (I). The As—O bond lengths, that is 1.6709(13) Å in (I), and 1.672(4) and 1.663(4) Å in (II), are equal within experimental errors suggesting little influence exerted by the Sn-bound halide atom upon the mode of coordination of O=AsPh3. Such invariance in the As=O bond lengths is consistent with that noted previously for analogous P=O bonds in phosphineoxide adducts of organotin species [9].

In the molecular packing of (I), As-phenyl-C—H⋯Br contacts [C34—H34⋯Br1i: H34⋯Br1i = 2.91 Å, C34⋯Br1i = 3.752(2) Å with angle at H34 = 149° for symmetry operation (i) −1 + x, −1 + y, z] lead to supramolecular chains aproximately parallel to [3 5 −13]. The connections between the chains are of the type phenyl-C—H⋯π(phenyl). Thus, Sn—phenyl-C—H⋯π(As-phenyl) [C16—H16⋯Cg(C31—C36)ii: H16⋯Cg = 2.75 Å with angle at H16 = 142° and C17—H17⋯Cg(C24—C30)iii: H17⋯Cg = 2.91 Å with angle at H17 = 130° for (ii) 1 – x, 1 – y, 2 – z and (iii) x, 1 + y, z] and As—phenyl-C—H⋯π(Sn-phenyl) [C29—H29⋯Cg(C7—C12)iv: H29⋯Cg = 2.68 Å with angle at H29 = 131° for (iv) 2 – x, 1 – y, 2 – z] are apparent. The layers interdigitate along the c-axis allowing for π-stacking interactions between centrosymmetrically-related Sn-bound phenyl rings [Cg(C1—C6)⋯Cg(C1—C6)v = 3.9112(13) Å for (v) 1 – x, 1 – y, 1 – z]. It is noted that the phenyl rings are off-set with a slippage of 1.75 Å [10].

The lack of directional interactions in the crystal of (I) is reflected in the analysis of the calculated Hirshfeld surfaces and two-dimensional fingerprint plots (overall and decomposed). The calculations were performed with Crystal Explorer 17 [11] following standard protocols [12]. The specified H⋯Br contacts leading to the supramolecular chain contribute 7.5% to the overall surface whereas the C⋯H/H⋯C contacts, largely corresponding to the C—H⋯π(phenyl) and π⋯π interactions, contribute 30.7% of all contacts. Small contributions of 1.5%, due to C⋯C contacts, and 0.3%, due to C⋯Br/Br⋯C contacts, are also noted. However, the most significant contribution, that is, 60.0%, arise from H⋯H surface contacts.
