In the title compound, C20H19O4, the benzene rings, linked via five methyl­ene C atoms, form a dihedral angle of 77.28 (6)°. In the crystal, mol­ecules are linked via pairs of weak C—H⋯O inter­actions [graph set R22(6)] into dimers that are further connected by additional weak C—H⋯O interactions [graph sets R22(14), R22(26) and R22(6)].

Comment top

The aldehydes represent important class of organic compounds that are used for the condensation reaction with amines to form Schiff bases. Therefore, we have decided to explore the capability of novel dialdehydes, namely 4-[5-(4-formylphenoxy)pentoxy]benzaldehyde, as starting material for the synthesis of some novel Schiff bases. Dialdehydes have recently been investigated as valuble precursors for condensation reactions with amines (Ilhan et al. 2007; Ma & Cao 2011; Dehno Khalaji et al. 2011). Such condensation reactions can lead to the formation of macrocyclic ligands or complex compounds, by methods of template synthesis (Ilhan et al. 2007; Keypour et al. 2008; Ma & Cao 2011).

In the title molecule two formylphenoxy groups are linked by five methylene C atoms and the dihedral angle between benzen ring is 77.28° (Figure 1.). In the crystal, the molecules are linked into dimers via weak C—H···O hydrogen bonding into a staircase-like motif (Figure 2.). A similar motif in dialdehydes was observed by Narasimha Moorthy et al. (2005). Additional stabilization of the crystal structure is accomplished by a number of weak C— H···O hydrogen bonding interactions [graph set: R22(14), R22(26), R22(6)] (Bernstein et al. 1995). O1 and O4 are involved in the formation of two different motifs: dimer formation [graph set R22(6)] and ring formation [graph set R22(26)]; specifically: O1···(C12— H12B, C19— H19) and O4···(C8— H8B, C1— H1) and thus making them bifurcated (Table 1).

Experimental top

p-hydroxybenzaldehyde (50 mmol) and K2CO3 (50 mmol) were mixed in 50 ml DMF and the mixture was brought to brisk reflux. 25 mmol of pentane-1,5-dibrom dissolved in 10 ml of DMF were added and the reaction mixture was refluxed for 4 h and stired at room temperature for additional 2 h. After the reaction was completed, 300 ml of demineralized water were added and the resulting percipitate was filtered and washed with plenty water. Single crystals suitable for X-ray diffraction were grown via liquid diffusion of water into 1,4-dioxane solution of title compound.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with C—H = 0.93 - 0.97 Å and with Uiso(H) = 1.2 times Ueq(C).

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.
