In the title compound, C₂₅H₂₇NO₅, each of the cyclohexenone rings adopts a half-chair conformation, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms. In the crystal, weak C—H⋯O hydrogen bonds link molecules into chains parallel to the c axis.

Comment top

As part of our ongoing study of the substituent effect on the solid state structures of xanthene derivatives (Cha et al., (2012). We present here the crystal structure of the title compound (I) (Fig. 1).

In (I) (Fig. 1), the bond lengths and angles are normal and correspond to those observed in related structures (Cha et al., 2012). All two cyclohexenone rings in (I) display half-chair conformation, whereas the pyran ring adopts a boat conformation.

In the crystal, weak intermolecular C17—H17···O5 hydrogen bonds into chains parallel to the c axis.

Experimental top

To solution of (E)-2.2-(3-(2-Nitrophenyl)prop-2-ene-1,1-diyl)bis (3-hydroxy-5,5-δimethylcyclohex-2-enone) (1.25 mmol) in methanol (12.5 ml) was added catalytic amount of sulfuric acid under nitrogen atmosphere. After stirring for 3 h, the solvent was evaporated and the remaining residue dissolved in ethyl acetate. The mixture was neutralized with saturated sodium bicarbonate and the solution was extracted with ethyl acetate. The resulting residue solid was purified by recrystallization from a mixture of ethanol and methylene chloride (1:1) to afford colorless block type crystals suitable for X-ray analysis.

Special details top

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 was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F². R-factor (gt) are based on F. The threshold expression of F² > 2.0 σ(F²) is used only for calculating R-factor (gt).
