Bis[μ-2-(phenylsulfanyl)anilido-κ²N:N]bis[bis(tetrahydrofuran-κO)lithium]

The title compound, [Li₂(C₁₂H₁₀NS)₂(C₄H₈O)₄], exists as a dimer in the solid state, with a central four-membered Li₂N₂ ring that is planar by crystallographic inversion symmetry. The Li atoms are bridged by the N atoms of two anilide ligands, and each Li atom is coordinated by two O atoms from tetrahydrofuran ligands, resulting in a distorted tetrahedral N₂O₂ environment. One of the tetrahydrofuran rings is disordered over two sets of sites in a 0.665 (16):0.335 (6) ratio.

Keywords: crystal structure; lithium anilide; thioaniline.

Experimental top

A solution of 2-phenylthioaniline (668 mg, 3.34 mmol) in 3 ml of dry tetrahydrofuran was frozen. Upon melting, 1.41 ml of a 2.5 M n-butyllithium solution in hexanes (3.53 mmol) was added dropwise. After stirring for 30 minutes at room temperature, 7 ml of dry pentane was added and the solution was stirred for additional 1.5 h. The resulting precipitate was isolated via vacuum filtration as a white powder (589 mg, 84% yield). ¹H NMR (400 MHz, C₆D₆): δ 7.60 (d, J = 7.2 Hz, 1 H, Ar-H), 7.24 (d, J = 7.6 Hz, 2 H, Ar-H), 7.17 (dt, J = 7.6 Hz, 1.6 Hz, 1 H, Ar-H), 7.14 (t, J = 7.6 Hz, 2 H, Ar-H), 6.77 (m, 2H, Ar-H), 6.38 (t, J = 7.2 Hz, 1 H, Ar-H), 3.68 (br s, 1 H, NH), 3.33 (m, 8 H, OCH₂), 1.25 (m, 8 H, CH₂); ¹³C NMR (100 MHz, C₆D₆): δ 165.8, 139.9, 138.2, 131.1, 128.9, 127.9, 125.3, 123.9, 117.7, 110.1, 67.5, 24.9. A sample suitable for single-crystal X-ray analysis was grown from pentane/tetrafuran layering.

Structure description top

Lithium amide complexes can lead to ladder-shaped conformations with solvation of the lithium atom often controlling the oligimerization/polymerization of the lithium complex (Clegg et al., 1995). Herein, we report the crystal structure of the lithium 2-(phenylthio)aniline bis(tetrahydrofuran) dimer. In the crystal, the dimerization results in a centrosymmetric Li₂N₂ ring (Fig. 1), with Li—N—Liⁱ and N—Li—Nⁱ [symmetry code: (i) −x, −y + 1, −z + 1] angles of 75.65 (10) and 104.35 (13)°, respectively, that are consistent with similar dimers (von Bülow et al., 1996, 2004; Cole et al., 2002). The dihedral angle between the least-squares planes of the Li₂N₂ ring and the aniline aromatic ring is 84.14 (12)°, and the dihedral angle between the two aromatic ring planes in the 2-(phenylthio)anilide is 79.52 (7)°, similar to that observed in the parent 2-(phenylthio)aniline (Mdluli et al., 2016). No π–π interactions are noted between the aromatic rings. The packing of the molecules in the title compound is shown in Fig. 2.

Special details top

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