Abstract top

In the xanthenone system of the title compound, C23H20O4, the pyran ring has a maximum deviation of 0.111 (1) Å from planarity and the outer cyclohexene ring exhibits a puckered conformation. The three methylene C atoms of the cyclohexene ring bonded to the pyran unit are disordered over two sets of sites [occupancies = 0.570 (3) and 0.430 (3)]. In the crystal, molecules are linked by C-H...O and O-H...O hydrogen bonds, forming a two-dimensional network parallel to (110). A C-H...[pi] interaction occurs between these networks.

Comment top

Xanthene derivatives have been used as antibacterial, antiviral, antitumor and anti-inflammatory agents (Zare et al., 2012). These compounds also have applications as dyes in laser technology (Menchen et al., 2003a,b), and as pH sensitive fluorescent materials for the visualization of biomolecules (Sarma & Baruah, 2005). Extending our previous studies of xanthenones (Abdelhamid et al., 2011; Mohamed et al., 2011, 2012), we report herein the synthesis and crystal study of a new of xanthenone derivative.

In the title compound shown in Fig. 1, the pyran ring (O1/C1/C10—C12/C17) has a maximum deviation of 0.111 (1) Å from planarity and the outer cyclohexene ring (C12–C17) of the xanthenone moiety is puckered with the puckering parameters (Cremer & Pople, 1975) of Q T = 0.455 (2) Å, θ = 124.4 (2) and φ = 352.8 (3)°. The three methylene C atoms (C20/C21/C22) of the other cyclohexene ring attached to the pyran moiety at atom C11 are disordered over two sets of sites with a ratio of refined occupancies of 0.570 (3): 0.430 (3) and both components of the disordered cyclohexene ring are puckered [puckering parameters: Q T = 0.445 (6) Å, θ = 48.7 (6) and φ = 183.8 (10)° for major component (C18/C19/C20B–C22B/C23), and Q T = 0.471 (8) Å, θ = 130.2 (8) and φ = 353.3 (13)° for minor component (C18/C19/C20A–C22A/C23)].

The bond lengths in the title compound are within normal ranges (Allen et al., 1987) and are comparable those of similar compounds (Li et al., 2004; Abdelhamid et al., 2011; Çelik et al., 2009; Mohamed et al., 2011, 2012; Reddy et al., 2009).

In the crystal structure, C—H···O and O—H···O hydrogen bonds link the neigbouring molecules (Table 1), forming two dimensional networks parallel to the ab-plane (Figs. 2 & 3). A C14—H14B···π interaction also exists between these planes.

Experimental top

The title compound was obtained as the main product during a three component reaction of 1 mmol (206 mg) 4-nitro-2-(trifluoromethyl)aniline, 1 mmol (172 mg) 2-hydroxy-1-naphthaldehyde and 1 mmol (112 mg) 1,3-cyclohexandione in 50 ml ethanol. The reaction mixture was refluxed for 7 h at 351 K. On cooling, the resulting solid was collected, washed with cold ethanol and dried by filtration. The crude product was crystallized by the slow evaporation method over 24 h using ethanol as a solvent. M.p. = 517 K, yield = 95%.

Refinement top

The hydroxyl H atoms were found from a difference Fourier map and refined freely. The C-bound H-atoms were refined using a riding model with C—H = 0.95 - 1.00 Å and Uĩso(H) = 1.2Ueq(C). The three methylene C atoms (C20/C21/C22) of the other cyclohexene ring bonded to the pyran moiety are disordered over two sets of sites with a ratio of refined occupancies of 0.570 (3): 0.430 (3) [in the refinement, DFIX and EADP instructions were used for the disordered atoms].
