In the octahydroxanthenedione unit of the title compound, C₃₁H₂₇NO₆, the central dihydropyran ring shows an envelope conformation, while the bilateral cyclohexene and cyclohexane rings adopt a half-boat conformation and a chair conformation, respectively. The nitrobenzene ring is twisted with respect to the two benzene rings, making dihedral angles of 63.1 (1) and 63.0 (1)°. In the crystal, O—H⋯O hydrogen bonds link the molecules into supramolecular chains propagating along the a-axis direction.

Keywords: crystal structure; xanthene; hydrogen bonding.

1. Chemical context

Xanthenes are important biologically active heterocyclic compounds, which possess anti-inflammatory, antibacterial and antiviral activities (Shakibaei et al., 2007 ; Lambert et al., 1997 ). Many studies have been carried out on xanthene derivatives (Knight & Little, 2001 ; Jha & Beal, 2004 ; Lu et al., 2011 ; Cui et al., 2012 ; Wang et al., 2015 ). Herein, we report the synthesis and the crystal structure of the title xanthene derivative.

2. Structural commentary

The molecular structure of the title compound is shown in Fig. 1. The C1—O1 and C15—O2 bond lengths are 1.234 (4) and 1.202 (4) Å, respectively. The central dihydropyran ring shows an envelope conformation with atom C19 as the flap, while the bilateral cyclohexene and cyclohexane rings adopt a half boat conformation and a chair conformation, respectively. The nitrobenzene ring is twisted with respect to the C7–C10 and C20–C25 benzene rings, making dihedral angles of 63.1 (1) and 63.0 (1)°, respectively.

3. Supramolecular features

In the crystal (Fig. 2), the molecules are linked by O—H⋯O hydrogen bonds (Table 1), generating supramolecular chains propagating along the a-axis direction.

4. Database survey

A search of the Cambridge Structural Database for 10a-hydroxy-3,4,5,6,7,8a,9,10a-octahydro-1H-xanthene-1,8(2H)-dione gave 16 hits. None of them are substituted at the 3,6-position with two phenyl groups. Several compounds substituted at the 9-position with an aryl group are similar to the title compound, for example, 9-(2,6-dichlorophenyl)-4a-hydroxy-3,3,6,6-tetramethyl-1,2,3,4,4a,5,6,7,8,9a-decahydroxanthene-1,8-dione (Bolte et al., 2001 ), 9-(2,3-dichlorophenyl)-4a-hydroxy-3,3,6,6-tetramethyl-3,4,4a,6,7,9,9a,10-octahydroanthracene-1,8(2H,5H)-dione (Mohammadi Ziarani et al., 2008 ) and 9-(2-chlorophenyl)-4a-hydroxy-3,4,4a,5,6,7,9,9a-octahydro-1H-xanthracene-1,8(2H)-dione (Liu et al., 2014 ).

5. Synthesis and crystallization

The title compound was synthesized in accordance to our previous procedure (Wang et al., 2015). 5-Phenylcyclohexane-1,3-dione (7.52 g, 40 mmol) and 3-nitrobenzaldehyde (20 mmol) were dissolved in the mixture of methanol (10 ml) and ethanol (10 ml) in the presence of trace L-proline (5 mmol) and stirred for 4 h. After completion of the reaction, the white solid products were filtered under reduced pressure and washed with ethanol (78% yield). m.p. 445.15–447.15 K. IR (KBr pellets, cm⁻¹): 3370 (O—H), 1648 (C=O), 1562 (C=C). MS (ESI) m/z: 510.2 [M + H⁺]. ¹H NMR (DMSO-d₆, 400 MHz): δ 2.56–2.92 (m, 8H, 2a-H, 7a-H, 2b-H, 7b-H, 4a-H, 5a-H, 4b-H, 5b-H); 3.43 (m, 2H, 6-H, 3-H); 5.46 (m, 1H, 9-H); 7.14 (m, 2H, 11-H, 10-OH); 7.22–8.02 (m, 14H, PhH). Analysis calculated for C₃₁H₂₇NO₆: C 73.07, H 5.34, N 2.75%; found: C 72.92, H 5.30, N 2.65%. Single crystals of the title compound were obtained by slow evaporation from an ethanol solution at room temperature in the form of colorless blocks.

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.
