2,2'-(1,3,5,7-Tetraoxo-1,2,3,5,6,7-hexahydropyrrolo[3,4-f]isoindole-2,6-diyl)diacetic acid N,N-dimethylformamide disolvate
The asymmetric unit of the title compound, C14H8N2O8·2C3H7NO or L·2DMF (DMF = N,N-dimethylformamide), contains one half of the centrosymmetric molecule L and one solvent molecule, which is disordered between two orientations in a 0.555 (4):0.445 (4) ratio. Intermolecular O-H
O hydrogen bonds link one L and two DMF molecules into a centrosymmetric hydrogen-bonded cluster. The crystal packing is further stabilized by weak intermolecular C-H
O hydrogen bonds.

2,2'-(1,3,5,7-Tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6-diyl)diacetic acid was synthesized according to the literature (Barooah et
al., 2006). N,N'-dimethylformamide (DMF) 5 ml was added
into a
solution of compound mentioned above 0.1 mmol in 20 ml MeOH. The resultant
colourless solution was filtered. Crystals suitable for X-ray analysis were
formed after three days at room temperature.
All H atoms were placed in calculated positions and included in a riding-model
approximation, with C—H = 0.93 - 0.97 Å, O—H = 0.82 Å and
Uiso(H)= 1.2-1.5 Ueq of the parent atom.
The solvent molecule is disordered between two orientations with the
occupancies refined to 0.555 (4) and 0.445 (4), respectively.
The hydroxy H atom is also disordered between two positions - H3A and
H4B - with the same occupancies, respectively.

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. |

Interest in the derivatives of diimide such as pyromellitic diimides, naphthalene diimides, and perylene diimides has arisen because of their potential applications for supramolecular and new functional materials (Bhosale et al., 2008). There have been a number of studies investigating the host–guest chemistry about pyromellitic diimide (Gabriel & Iverson, 2002; Ghosh & Ramakrishnan, 2005; Kimizuka et al., 1995). Supramolecular host of L and inclusion compounds with aromatic guests have been described (Barooah et al., 2006). In this paper, we report the crystal structure of the title compound, obtained by the recrystallization in DMF-MeOH.
In the molecule L (=2,2'-(1,3,5,7-tetraoxo-5,7-dihydropyrrolo[3,4- f]isoindole-2,6-diyl)diacetic acid), two acetic acid groups are placed on upper and lower sides of the rigid conjugate plane (Fig. 1). Intermolecular O—H···O hydrogen bonds (Table 1) link one L and two solvent molecules into centrosymmetric hydrogen-bonded cluster. The crystal packing is further stabilized by weak intermolecular C—H···O hydrogen bonds (Table 1).
