Source of material

A solution of 1,4-dibromobenzene (Sigma, 23.6 g, 0.1 mol) in dry ether (50 mL) was added dropwise to magnesium turnings (Merck, 2.4 g, 0.1 mol) suspended in dry ether (150 mL) in a three necked flask equipped with a reflux condenser, a nitrogen supply source and a dropping funnel filled with the 1,4-dibromobenzene solution. After the addition was complete, the reaction mixture was refluxed with stirring for 2 h. This was followed by the addition of dimethyltin dichloride (Merck, 11 g, 0.05 mol). The reaction mixture was subsequently refluxed for 2 h. This was followed by hydrolysis with 20% aqueous ammonium chloride solution (200 mL). The organic layer was separated, washed with distilled water and dried over molecular sieves. The solution was then filtered and concentrated to obtain a white crystalline solid. The precipitate was recrystallised from chloroform and colourless crystals were obtained from the slow evaporation of the solvent. Yield: 8.05 g (34.9%). M.pt (Stuart SMP30 digital melting point apparatus; uncorrected): 524–526 K (dec). IR (Bruker Vertex 70v FTIR Spectrometer; cm−1): 2930 (s) ν(C–H), 1495 (m) ν(C=C). 1 H NMR (Bruker Ascend 400 MHz NMR spectrometer; CDCl3; ppm relative to Me4Si): δ 0.98 (s, 6H, CH3), 7.13–7.59 (m, 8H, Ph–H). 13 C{ 1 H} NMR (as for 1H NMR): 11.4 (CH3), 115.3, 123.7, 129.7, 137.5 (Ph–C).

Experimental details

The C-bound H atoms were geometrically placed (C–H = 0.95–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C).

Comment

The title compound, Me2Sn(C6H4Br-4)2, hereafter (I), is only the third crystal structure containing the Sn(C6H4Br-4) fragment, the others being Sn(C6H4Br-4)4 [5] and the anion in the salt [4-Me2NC5H4NH][Me2SnBr2(C6H4Br-4)] [6]. The structure determination of (I) was undertaken as part of recent and on-going investigations of related 4-halophenyltin species [7, 8].

The molecular structure of (I) is shown in the Figure (70% displacement ellipsoids). The molecule lacks symmetry with the tin atom within a C4 donor set defined by two methyl-C and two phenyl-C atoms. The range of angles subtended at the tin atom is a low 104.88(10)°, for C2–Sn–C9, to a wide 116.74(10)°, for C1–Sn–C2, consistent with a distorted tetrahedral geometry for the tin atom. The Sn–C bond lengths are indistinguishable, ranging from 2.134(3) Å, for Sn–C1, to 2.147(3) Å, for Sn–C9. The dihedral angle between the phenyl rings is 68.47(12)°.

In the crystal, molecules assemble largely devoid of directional interactions according to an analysis based on PLATON [9]. Thus, methyl-C–H⋯π(C6H4Br) contacts [C1–H1c⋯Cg(C3–C8) i : H1c⋯Cg(C3–C8) i  = 2.74 Å with angle at H1c = 168° and C2–H2a⋯Cg(C9–C14) ii : H2a⋯Cg(C9–C14) ii  = 2.87 Å with angle at H2a = 125° for symmetry operations (i): x, y, 1 + z and (ii): 1 − x, 1 − y, 2 − z] are apparent and occur between molecules arranged in a zig–zag chain aligned along the c-axis. The most prominent contacts between chains are type II [10] Br⋯Br halogen bonding interactions [Br1⋯Br2 iii  = 3.6807(4) Å cf. the sum of the van der Waals radii = 3.70 Å [9]; C6–Br1⋯Br2 iii  = 172.36(9)° and C12 iii –Br2 iii ⋯Br1 = 93.79(7)° for (iii) −1 + x, y, −1 + z]. Additional Br⋯Br contacts are noted, at separations just greater than the sum of the van der Waals radii [Br1⋯Br2 iv  = 3.7459(4) Å for (iv): −1 + x, y, z].

Additional information on the molecular packing was obtained through an analysis of all surface contacts in the crystal of (I). This was accomplished by the calculation of the Hirshfeld surfaces and two-dimensional fingerprint plots (full and decomposed into individual contacts) using Crystal Explorer 17 [11] and literature protocols [12]. The Hirshfeld surface analysis indicated the dominance of hydrogen in the surface contacts, namely H⋯H [39.9%], Br⋯H/H⋯Br [26.8%] and C⋯H/H⋯C [26.2%]. The next most significant contacts are due to Br⋯Br [3.5%] and Br⋯C/C⋯Br [3.1%] contacts with a minor contribution from C⋯C [0.4%] contacts.
