The title compound, C18H20N2OS, displays whole-molecule disorder over two adjacent sets of sites with an occupancy ratio of 0.630 (11):0.370 (11). In each disorder component, the cyclohexyl ring shows a chair conformation with the exocyclic C—C bond in an equatorial orientation. The dihedral angles between the cyclohexyl ring (all atoms) and the naphthyl ring system are 36.9 (6) for the major component and 20.7 (12)° for the minor component. Each component features an intramolecular N—H⋯O hydrogen bond, which closes an S(5) ring. In the crystal, inversion dimers linked by pairs of N—H⋯S hydrogen bonds generate R22(8) loops for both components. Aromatic π–π stacking interactions [shortest centroid–centroid separation = 3.593 (9) Å] and a C—H⋯π interaction are also observed.
Keywords: crystal structure; whole-molecule disorder; thiourea derivatives; intramolecular N—H⋯O hydrogen bond; N—H⋯S hydrogen bonds; π–π stacking interactions; C—H⋯π interactions.

A solution of cyclohexane carbonyl chloride (1.4661 g, 10 mmol) in acetone (60 ml) was added drop wise to a suspension of potassium thiocyanate (0.9718 g, 10 mmol) in anhydrous acetone (60 ml). The reaction mixture was heated under reflux for 45 minutes and then cooled to room temperature. A solution of substituted naphthalen-1-amine (1.43 g, 10 mmol) in acetone (60 ml) was added and the resulting mixture was stirred for 2 h at room temperature. Hydrochloric acid (0.1 N, 500 ml) was added and the resulting white solid was filtered off, washed with water and dried in vaccum. The yield of the isolated product was 89%, giving colourless blocks.
All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances fixed in the range 0.93–0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for all other H atoms.

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. |

The design and synthesis of thiourea are of considerable interest because of their use in agriculture, medicine and analytical chemistry (J·H. Hu et al., 2011). Thiourea derivatives are driven by their potential as biological active compounds (Sun et al., 2006) and in the material application such as anti corrosion (Shen et al., 2006). As part of our own studies in this area, the crystal structure of the title compound has been determined and the results are presented herein.
For the major disorder component, the cyclohexane ring (C13—C18) adopts chair conformation [puckering amplitudes and smallest displacement parameters are q = 0.568 Å, θ = 177.7 (8)°, ϕ = 19 (29)° and ΔCs = 0.9 (14) Å]. Similarly, for the minor disorder component, the cyclohexane ring (C13'—C18') adopts a chair conformation. [puckering amplitudes and smallest displacement parameters are q = 0.56 (3) Å, θ = 180 (3)°, ϕ = 354 (31)° and ΔCs = 3.0 (4) Å]. The dihedral angles between cyclohexane and benzene rings (C5—C8/C10) and (C5—C10) of naphthalene moiety are 37.0 (7)and 36.5 (7)° (major component). In the case of minor component, the dihedral angles between cyclohexane and benzene rings (C5—C8/C10)and (C5—C10) of naphthalene are 37.0 (7)and 36.5 (7)°, respectively. The molecular conformation is consolidated by an intramolecular N—H···O hydrogen bond, forming S(5) ring motif.
The crystal packing features N—H···S hydrogen bonds with the symmetry code: (i) 2 - x,-y,1 - z, which links the molecules into centrosymmetric dimers with graph-set descriptor of R22(8). The crystal packing also features C—H···π (Table 1) and π-π interactions (Cg2···Cg2ii = 3.593 (9) Å; Cg2 is the centroid of a ring C5—C10; symmetry code: (ii) 3 - x,1 - y,2 - z. The packing view of the title compound is shown in Fig. 3.
