(Received 5 December 2012; accepted 12 December 2012; online 15 December 2012)

In the title mol­ecule, C24H29NO4, the central ring of the acridinedione system adopts a flat boat conformation and the four essentially planar atoms of this ring [maximum deviation = 0.001 (2) Å] form a dihedral angle of 85.99 (12)° with the benzene ring. The two outer rings of the acridinedione system adopt sofa conformations. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules, forming a two-dimensional network parallel to (100).

Comment top

Acridines, the earliest known antibiotics, are toxic towards bacteria. Some acridinedione derivatives show good inhibition against the pathogen Vibrio isolate-I (Josephrajan et al., 2005). Certain acridine-1,8-diones exhibit fluorescence activities (Murugan et al., 1998) and a few acridinedione derivatives also show photophysical (Srividya et al., 1998) and electrochemical properties (Srividya et al., 1996). Thus, the accurate description of crystal structures of substituted acridinediones are expected to provide useful information on the role of substituents in influencing molecular conformation which has a direct relationship to biological activity. This paper deals with the crystal structure of a 4-hydroxy-3-methoxyphenyl substituted tetramethyl acridinedione, (I).

In (I) (Fig.1), all bond lengths and angles are normal and correspond to those observed in related structures (Balamurugan et al.,2009; Zhao & Teng 2008). The central ring (C4A/C5A/C8A/C9A/C9/N10) of the acridinedione moiety adopts a boat conformation (ΔCs(N10) = 0.129 & ΔCs (C5A—C8A) = 10.84) and the four essentially planar atoms (C4A/C5A/C8A/C9A) of this ring (maximum deviation 0.001 (2)Å for all atoms) forms a dihedral angle of 85.99 (12)° with benzene ring. Both the outer rings adopt sofa conformations (ΔCs (C6) = 1.55; ΔCs (C3) = 7.45) (Duax & Norton, 1975). In the crystal, O1—H1···O4i and N10—H10···O3ii hydrogen bonds (Table 1) link molecules to form a two-dimensional network parallel to (100) (Fig. 2).

Experimental top

In a 50 ml rounded bottom flask, a mixture of dimedone (2 mmole), 4-hydroxy, 3-methoxy benzaldehyde (1 mmole) and ammonium acetate (1.2 mmole) in mixture of aqueous ethanol (7 ml) was stirred at RT for 5 min. To this mixture 3-carboxymethyl-1-methylimidazolium(HSO4) (20 mol%) was added and the reaction mixture heated at 348-353K for 1.5 hrs. The progress of reaction was monitored by TLC. After completion of reaction, the mixture was cooled to RT and poured on iced water under stirring, The precipitate was filter and dried. The crude product were recrystallized from ethanol to afford X-ray quality crystals. M.P.: 568–571 K, Yield: 82%.

All H atoms were positioned geometrically and were treated as riding on their parent C atoms, with C—H distances of 0.93–0.96 Å and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

Experimental. CrysAlis PRO, Oxford Diffraction Ltd., Version 1.171.34.40 (release 27–08-2010 CrysAlis171. NET) (compiled Aug 27 2010,11:50:40) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

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.
