In the mol­ecule of the title compound, C20H16N2O5, the phthalimide fragments are almost planar, with r.m.s. deviations of 0.018 and 0.020 Å, and make a dihedral angle of 53.64 (3)°. The mol­ecular and crystal structures are stabilized by a weak inter­molecular C—H⋯O, C—H⋯π and C=O⋯π [2.883 (1) Å] inter­actions and aromatic π–π stacking inter­actions with a centroid–centroid distance of 3.6189 (7) Å.

Comment top

The asymmetric unit contains one molecule of the title compound (Figure 1). In the molecule phthalimide fragments are planar, with r.m.s. deviations of 0.018Å and 0.020Å, respectively. The angle between planes is 53.64 (3)°. The observed structure is stabilized by weak C—H···O and C-H···π(ring) hydrogen bonds (Table 1), as well as C=O···π(ring) (C4=O2···Cg2 distance is 2.883 (1), where Cg2 is N2C13C14C15C16 ring centroid) and aromatic π···π stacking interactions. A centrosymmetric π···π stacking interactions are observed between maleimide rings (Cg2···Cg2i distance is 3.4805 (9) Å, where i = 1-x, -y, -z) and benzene rings (Cg3···Cg3ii distance 3.6189 (7)Å, where Cg3 is C2C3C5C6C7C8 ring centroid, ii = 1-x, -y, 1-z) (Figure 2).

Experimental top

The title compound is received by the slightly modified technique (Yatsimirskii et al.,1987). 24 g (0.12 mole) potassium phthalimide and 8 ml (0.05 mole) β,β'-dichloroethyl ether were taken in a three-necked round-battomed flask supplied with a reflux condenser and a mechanical stirrer. Reaction is carried out at 463-473 K within 2.5 hours by stirring. After corresponding chemical treatments (Yatsimirskii et al.,1987) reaction product was recrystallized from 1:1 mixture of ethanol and chloroform. 13.99 g (56 %) title compound , with m.p. of 421-423 K was received.

Refinement top

Carbon-bound H atoms were positioned geometrically and treated as riding on their C atoms, with C—H distances of 0.93 Å (aromatic) and 0.97 Å (CH2) and were refined with Uiso(H)=1.2Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
