Comment top

An X-ray study of the title compound, (I), was of interest because xanthene derivatives have been well documented as biogenic precursors (Vinod & Gupta, 1979) and neuroleptic (Lassen et al., 1980) and antiallergic (Pfister, 1980) agents. They possess antiviral activity (Carr et al., 1976). These derivatives act as a potent human CCRI receptor antagonists (Naya et al., 2003).

In the title molecule (Fig. 1), bond lengths in the aromatic rings (C and E), the cyclohexane ring (A) and the morpholine ring (D) have normal values (Allen et al., 1987). The geometry of the pyran ring in the xanthene moiety (Table 1) is comparable to that observed in other xanthene derivatives (Jeyakanthan et al., 1999; Miao et al., 1996). The sum of the bond angles around N15 of 337.2 (2)° is indicative of sp3 character of the atom. The aromatic rings E and C are almost perpendicular to each other with a dihedral angle of 85.5 (1)°. The pyran ring in the xanthene moiety adopts a half-chair conformation with asymmetry parameter DC2(C7—C2) = 0.003 (1) (Nardelli, 1983). The cyclohexane ring (A) and the morpholine ring (D) both adopt chair conformations. The molecular structure is influenced by weak N—H···N and C—H···O hydrogen bonds. The crystal structure is stabilized by C—H···O interactions and C—H···π interactions involving the symmetry-related aromatic ring C (Table 2 and Fig. 2).

Experimental top

A solution of 0.3 g of cyclohexanone, 0.27 g of morpholine and catalytic amount of InCl3 in 20 ml of acetonitrile was refluxed for 3 h. The reaction mixture was cooled to room temperature under a nitrogen atmosphere and 0.6 g of o-hydroxybenzylideneaniline was added. The reaction mixture was stirred at ambient temperature for 20 min. After completion of the reaction, the reaction mixture was quenched by addition of water and extracted with ethyl acetate. The combined organic layer was dried over anhydrous Na2SO4, filtered and concentrated under vacuum. The crude crystalline product was recrystallized using ethyl acetate to yield the title compound. The melting point of the title compound is 429–431 K.

Refinement top

H atoms were positioned geometrically with C—H distances fixed in the range 0.93–0.98 Å and N—H distance at 0.86 Å. They were allowed to ride on their parent atoms with the isotropic displacement parameter Uiso(H) set at 1.2Ueq(C or N). The final cycles of refinement showed the highest difference peak of 0.97 e Å−3, much larger than the absolute value of the deepest hole (−0.35 e Å−3). This peak was located at a distance of 1.27 Å from both C8 and N21. Possibility of a disordered aminophenyl substituent (N21/C22–C27) was examined but we were unable to find a suitable disorder model. Reflections were measured to θmax of 27.97° with 91% completeness, but the data are 97% complete to 25°.

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.
