In the title compound, C21H21N3OS·C3H7NO, the carbonitrile molecule is built up of two fused six-membered rings and one six-membered ring linked through a spiro C atom. The 1,3-diaza ring adopts an and the cyclohexane ring adopts a chair conformation. The dihedral angle between the aromatic rings is 46.7 (3)°. In the crystal, the components are linked by N—H⋯O hydrogen bonds.

To a solution of cyclohexanone (3 ml) and sodium hydroxide (0.3 mmol) were added 3-amino-5-(methylthio)biphenyl-2,4-dicarbonitrile (0.1 mmol). The mixture was heated at 373 K for 2.0 h. The reaction mixture was cooled with ice water (20 ml) and then filtered to give the title compound. The product was recrystallizated from a mixed solvent (ethanol:N,N-dimethylformamide 1:3) to obtain colorless single crystals. M.p. 572–573 K. Spectra data: IR (KBr): 3317, 3219, 2933, 2216, 1650, 1585, 1550, 1413, 771, 709 cm-1. 1H-NMR (DMSO-d6, p.p.m.): 0.92–1.84 (10H, m, C5H10), 2.38 (3H, s, SCH3), 6.50(1H, s, NH), 6.61 (1H, s, ArH), 7.50–7.61 (5H, m, ArH), 8.29 (1H, s, NH).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 molecular structure of 5'-methylthio-4'-oxo-7'-phenyl-3',4'-dihydro-1'H-spiro[cyclohexane-1, 2'-quinazoline]-8'-carbonitrile(I) is built up with one six membered ring and two fused six membered rings and a six membered ring linked through a spiro C atom (Fig. 1). The ring of C1, C2, C3, C4, C5, C6 exists in an chair conformation, and the C6 atom displaced by 0.647 (6)Å from the ring of C1, C2, C4, C5 (planar within 0.019 (5) Å), while C3 atom displaced by 0.669 (8) Å. The 1,3-diaza ring exists in an envelope conformation, and the C6 atom displaced by 0.476 (5)Å from the rest of the atoms of the 1,3-diaza ring (planar within 0.013 (5) Å). The dihedral angle between the plane (C14, C15, C16, C17, C18, C19) and the plane (C8, C9, C10, C11, C12, C13) is 46.7 (3)°. The angle between C9, S1, C20 is 102.83 (8) Å. The geometry of the fused rings compares well with the related spiro[cyclopentane-1,2'(1'H)-quinazolin]-4'(3'H)-one] (Zhang et al., 2008). The crystal packing is stabilized by intermolecular N—H···O and N—H···N bonds.
