Crystal structure of bis-(N-methyl-N-phenyl-amino)-tris-ulfane.

The title compound, C14H16N2S3, crystallized with two independent mol-ecules [(1 a ) and (1 b )] in the asymmetric unit. Both mol-ecules display a pseudo-trans conformation. The two consecutive S-S bond lengths of the tris-ulfane unit of mol-ecule (1 a ) are 2.06 (3) and 2.08 (3) Å, and 2.08 (3) and 2.07 (2) Å for mol-ecule (1 b ). Torsion angles about each of the two S-S bonds are 86.6 (2) and 87.0 (2)° for (1 a ), and -84.6 (2) and -85.9 (2)° for (1 b ). The core atoms, viz. the N-S-S-S-N moiety, of the two mol-ecules superimpose well if one is inverted on the other, but the phenyl groups do not. Thus, the two units are essentially conformational enanti-omers. In mol-ecule (1 a ), the two phenyl rings are inclined to one another by 86.7 (3)°, and in mol-ecule (1 b ), by 81.1 (3)°. In the crystal, mol-ecules are linked via C-H⋯π inter-actions, forming sheets lying parallel to (010).

Chemical context

The reactions of substrates with one or two sulfanyl chloride, acid chloride, and/or (alk­oxy­dichloro­meth­yl)sulfanyl moieties have been of inter­est to our laboratory for some time (Barany et al., 1983 ▸; Barany & Mott, 1984 ▸; Schroll & Barany, 1986 ▸; Schroll et al., 1990 ▸; Schroll et al., 2012 ▸). In some of these experiments, bis­[meth­yl(phen­yl)amino]­tris­ulfane was a component of more complicated mixtures of polysulfanes with varying numbers of S atoms. One such mixture was separated by preparative HPLC at 298 K, eluting with methanol–water (17:3). The fraction containing the title compound (dissolved in the eluting solvent) was cooled to 277 K, after which the tris­ulfane was obtained directly in crystalline form.

Structural commentary

The title compound, (1), was obtained in crystalline form after preparative HPLC, as described by Schroll & Barany (1986 ▸). The proposed mol­ecular structure of (1) was confirmed by single-crystal X-ray analysis at 173 K. The mol­ecules do not take advantage of the twofold axis provided as an available symmetry option by the Fdd2 space group. Instead, there are two mol­ecules, (1 ) and (1 ), in the asymmetric unit (Fig. 1 ▸), and both of them display a pseudo-trans conformation (see later). All bond distances and angles in both mol­ecules are within expected ranges. Selected geometric parameters for compound (1) are given in Table 1 ▸. The two consecutive S—S bond lengths (comprising the tris­ulfane) of mol­ecule (1 ) are 2.064 (3) and 2.078 (3) Å, and for mol­ecule (1 ) are 2.076 (3) and 2.067 (2) Å. These values are similar to the value of 2.07 Å reported for the S—S bond length in elemental sulfur (S8). Torsion angles about each of the two S—S bonds (comprising the tris­ulfane) are, respectively, 86.6 (2) and 87.0 (2)° for (1 ), and −84.6 (2) and −85.9 (2)° for (1 ). The core atoms, viz. the N—S—S—S—N moiety, of the two units superimpose well if one is inverted on the other, but the phenyl groups do not. Thus, the two units are essentially conformational enanti­omers. Moreover, with respect to the four measured torsion angles, which range in absolute value from 84.6 (2) to 87.0 (2)°, these are slightly smaller than the theoretical optimum of 90.0° (Pauling, 1949 ▸; Torrico-Vallejos et al., 2010 ▸). Finally, given the presence of three consecutive linearly connected sulfur atoms, representing two dihedral angles close to 90°, it is noteworthy that both of the mol­ecules in the asymmetric unit display a pseudo-trans conformation (torsion angles +,+ or -,- across the two S—S bonds). The theoretically possible pseudo-cis (torsion angles +,- or -,+) conformation (Meyer, 1976 ▸) was not observed for these structures.

Database survey

A search of the Cambridge Structural Database (CSD, Version 5.36, February 2015; Groom & Allen, 2014 ▸) revealed the presence of two compounds (see Fig. 3 ▸) that also have an N—S—S—S—N moiety, viz. bis­(oxamido)­tris­ulfane, (2) (CSD refcode GEHPUE; Brunn et al., 1988 ▸), and bis­[tert-but­yl(di-tert-butyl­fluoro­sil­yl)amino]­tris­ulfane, (3) (SOTLAO; Klingebiel et al., 1991 ▸). Unlike the title compound, (1), compounds (2) and (3) each have a unique conformation in the unit cell (Z′ = 1). Selected geometric parameters of (1) and the comparison compounds, (2) and (3), are given in Table 1 ▸. While the average S—S bond length of the title compound is ca 2.07 Å, the corresponding value is longer (2.09 Å) in (3) and shorter (2.04 Å) in (2). The absolute value of the average torsion angle of the title compound (1) is ca 86.0°, while the corresponding value is larger (93.2 and −89.5°) and closer to the theoretical optimum in (2), and significantly larger (109.7 and 95.9°) in (3).

Note regarding nomenclature: In the discussion above, a consistent nomenclature scheme has been used that differs from the names used in the original publications, viz. bis(oxamido)­tris­ulfan, (2) (Brunn et al., 1988 ▸) and 1,3-bis­[tert-but­yl(di-tert-butyl­fluorsil­yl)amino]­tris­ulfan, (3) (Klingebiel et al., 1991 ▸).

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.

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.
