Abstract top

In the title compound, C28H38N2O3, the central ring of the acridinedione system adopts a boat conformation, while one of the outer rings adopts a half-chair conformation and the conformation of the other outer ring is between a sofa and a half-chair. The acridinedione system is buckled, with an angle of 22.01 (3)°. The crystal packing comprises layers of molecules laid parallel to the ac plane, being reinforced by an intermolecular C-H...O interaction.

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 precise description of a 4-methoxyphenyl substituted tetramethyl acridinedione, (I).

The planar phenyl ring of the substituent moiety at C9 is perpendicular to the acridinedione moiety forming a dihedral angle of 88.21 (6)°, Fig. 1. The dimethylaminoethyl group is also oriented 80.0 (1)° to the acridinedione plane. The substitutuents at the C9 and N1 positions are cis oriented with respect to the acridinedione moiety and project opposite to the fold in the acridinedione moiety. The central ring of the acridinedione moiety adopts a boat conformation (ΔCs (N1) = 0.028 (1)° & ΔCs (C6—C1) = 0.057 (1)°). One of the outer rings (C1—C6) adopts a half-chair conformation (ΔC2 (C1—C6) = 0.045 (1)°) and that of the other outer ring (C10—C15) ring is between a sofa and half chair conformation (ΔCs (C10) = 0.066 (1)° & ΔC2 (C10—C15) = 0.061 (1)°) (Nardelli, 1983). The crystal packing consists of layers of molecules laid parallel to the ac-plane. Only one of the two keto-O atoms participates in a C—H···O contact, Table 1.

Experimental top

Light-yellow crystals were obtained by recrystallization from an ethanol solution of (I).

Refinement top

H atoms were placed in geometrically idealized positions and allowed to ride on their parent atoms, with C – H distances in the range 0.93 – 0.98 Å, and with Uiso(H) = 1.2 or 1.5 (for methyl-H) times Ueq(C).

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 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.
