The title compound, C21H21NO5, crystallizes with two molecules in the In each molecule, the central 1,4-dihydropyridine ring adopts a shallow sofa conformations (with the C atom bearing the phenol ring as the flap), whereas the pendant cyclohexene rings both have twisted-boat conformations. Each molecule features an intramolecular O—H⋯O hydrogen bond, which closes an S(8) ring. In the crystal, the molecules are linked by O—H⋯O, C—H⋯O and C—H⋯π interactions, forming a three-dimensional network.

A mixture of ethyl 2-[9-(2-hydroxyphenyl)-1,8-dioxo-2,3,4,5,6,7,8,9-octahydroacridin- 10(1H)-yl) acetate (2.0 g, 0.005 mol) and a solution of NaOH (0.4 g, 0.01 mol) in (40 ml) ethanol was heated under reflux for 5 h. The reaction mixture was poured onto cold water and acidified with conc. HCl. The separated solid was filtered off, dried and crystallized from ethanol to afford dark red prisms.

The hydroxyl hydrogen atoms were found from a difference Fourier map and the O—H distances were restrained to 0.82 (2) Å, using the DFIX option and included in the structure-factor calculations with Uiso(H) = 1.5Ueq(O). The remaining H atoms were placed in calculated positions with C—H = 0.93 - 0.98 Å, and refined as riding with Uiso(H) = 1.2Ueq(C).
Acridines and acridinium salts are highly fluorescent (Szymanska et al., 2000), and as electron acceptors in photochemical processes (Fox & Chanon, 1988). In addition, acridine derivatives have found application as antimalarial, and antitumour agents (Groundwater & Munawar, 1997; Cane et al., 1991). In this context, we report herein the synthesis and

In the molecules (A and B), the central 1,4-dihydropyridine rings (N1/C5–C9 and N1'/C5'–C9') of the 1,2,3,4,5,6,7,8,9,10-decahydroacridine ring systems (N1/C1–C13 and N1'/C1'–C13') adopt nearly a chair conformation [the puckering parameters are QT = 0.261 (2) Å,In the π interactions, forming a three-dimensional network (Table 1, Fig. 2).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

Acridines and acridinium salts are highly fluorescent (Szymanska et al., 2000), and as electron acceptors in photochemical processes (Fox & Chanon, 1988). In addition, acridine derivatives have found application as antimalarial, and antitumour agents (Groundwater & Munawar, 1997; Cane et al., 1991). In this context, we report herein the synthesis and crystal structure of the title compound.
Fig. 1 shows two molecules (A and B) of the title compound in the asymmetric unit. In the molecules (A and B), the central 1,4-dihydropyridine rings (N1/C5–C9 and N1'/C5'–C9') of the 1,2,3,4,5,6,7,8,9,10-decahydroacridine ring systems (N1/C1–C13 and N1'/C1'–C13') adopt nearly a chair conformation [the puckering parameters are QT = 0.261 (2) Å, θ = 110.0 (4) °, φ = 360.0 (5) ° and QT = 0.337 (2) Å, θ = 108.1 (3) °, φ = 4.8 (4) °, repsectively], which the cyclohexene rings (C1–C6, C8–C13 and C1'–C6', C8'–C13') of the 1,2,3,4,5,6,7,8,9,10-decahydroacridine ring systems have a twisted-boat conformation [for molecule A, the puckering parameters are QT = 0.470 (4) Å, θ = 120.0 (4) °, φ = 286.9 (4) ° and QT = 0.460 (3) Å, θ = 60.2 (4) °, φ = 196.0 (4) °, repsectively, and for molecule B, QT = 0.465 (3) Å, θ = 120.0 (4) °, φ = 288.3 (4) ° and QT = 0.474 (3) Å, θ = 61.3 (4) °, φ = 194.8 (4) °, respectively].
In the crystal structure, adjacent molecules are connected by O—H···O, C—H···O and C—H···π interactions, forming a three-dimensional network (Table 1, Fig. 2).
