N-[(3-Ethylphenyl)carbamothioyl]-2,2-diphenylacetamide

Abstract top

In the title molecule, C23H22N2OS, the diphenylacetyl and ethylbenzene groups adopt a trans-cis conformation, respectively, with respect to the S atom across the (S=)C-N bonds. This conformation is stabilized by an intramolecular N-H...O hydrogen bond and a weak C-H...S hydrogen bond. The ethyl-substituted benzene ring forms dihedral angles of 87.53 (15) and 73.94 (15)° with the phenyl rings. In the crystal, N-H...O hydrogen bonds link molecules into chains along [100]. A weak C-H...[pi] interaction is also observed.

Comment top

Carbonylthiourea derivatives have been explored because they are reported to posses biological activities such as antibacterial, anti-fungal and antiviral (Zhong et al., 2008; Saeed et al., 2010). The crystal structure of the title compound is presented herein.

The molecular structure is shown in Fig. 1. The diphenylacetyl and ethylbenzene groups adopt a trans-cis configuration, respectively, with respect to the sulfur atom across the (S)C–N bonds. Intramolecular N2—H1N2···O1 and C21—H21A···S1 hydrogen bonds result in two S(6) graph-set motifs (Bernstein et al., 1995). The ethyl-substituted benzene ring (C16–C21) forms dihedral angles of 87.53 (15) and 73.94 (15)°, respectively with the C1–C6 and C8–C13 rings. The bond lengths (Allen et al., 1987) and angles are within normal ranges and comparable to related structures (Yusof et al., 2012a,b).

In the crystal molecules are linked into one-dimensional chains along the [100] via intermolecular N1—H1N1···O16i hydrogen bonds (Table 1). In addition, a weak C7—H7A···Cgii interaction is observed (Cg is the centroid of C8–C13).

Experimental top

An acetone (30 ml) solution of 3-ethylaniline (1.63 g, 13.5 mmol) was added to a round-bottom flask containing 2,2-diphenylacetyl chloride (3.10 g, 13.5 mmol) and ammonium thiocyanate (1.03 g, 13.5 mmol). The mixture was refluxed for 2.5h then filtered off and left to evaporate at room temperature. The colourless precipitate obtained was washed with water and cold ethanol. Colourless crystals suitable for X-ray analysis were obtained by recrystallization of the precipitate in DMSO.

Refinement top

N-bound H atom were located in difference maps and refined freely, [N–H = 0.82 (3) and 0.90 (3) Å]. The remaining H atoms were positioned geometrically [C–H = 0.95–1.00 Å] and refined using a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl group. In the final refinement one outlier was omitted (1 2 0).

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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 > σ(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.
