All reagents were of AR grade, available commercially and used without further purification. The mixture of terephthalaldehyde (0.67 g, 5 mmol), morpholine (1.74 g, 20 mmol) was heated and refluxed in ethanol (20 ml) for 5 h, and then the resulting solution was cooled to room temperature. After filtration, the filtrate was allowed to stand at room temperature. Upon slow evaporation, colorless block crystals suitable for X-ray diffraction analysis were isolated three days later.
All the H atoms on carbon were placed in calculated positions and refined using a riding model with C—H distance in the range 0.93 - 0.98 Å, and Uiso(H)= 1.2Ueq(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. |

Recently, much attention has been focused on morpholine-containing compounds due to their biological activity as well as chemical and industrial versatility (Bellon et al., 1996; Goodman & Jacobsen, 2002; Lanman & Myers, 2004). Herein, we report the synthesis and crystal structure of a new morpholine-containing compound, 1,4-bis(dimorpholinomethyl)benzene.
As shown in Fig. 1, the nitrogen atoms of four morpholine molecules are bonded to C9 and C9i[symmetry code, (i) 1 - x, 1 - y, 1 - z], respectively. The title molecule possesses a centre of symmetry at the centroid of the benzene ring. The bond lengths and bond angles in the title compound are within normal ranges. The dihedral angle between the plane formed by C9, N1, N2 and the benzene ring plane is 78.87 (9)°. The bond angle of N2—C9—N1 is 107.7 (1)° and the bond length of the backbone C9—C10 is 1.520 (2) Å, which are comparable with those reported in the references (Fujihara et al., 2002; Ma et al., 2005). The morpholine rings adopt the usual chair conformation. They are similar to those of 4,4'-di(morpholin-1-yl)azoxyfurazan (Averkiev et al., 2005) and 2,5-bis-(morpholinomethyl)hydroquinone (Ma et al., 2005). There are no significant contacts among the neighboring molecules, therefore, the molecules pack together only through van der Waals forces in the solid state.
