Comment

Polyimides are well known for their excellent thermal and oxidative stability as well as their excellent mechanical properties (Stoessel et al., 1998) suited for use as matrix resins, adhesives and coatings for high-performance applications in the aerospace and electronics industries (Nakamura et al., 2001). These advantages simultaneously give rise to low solubility and poor processability, which can be overcome by incorporation of new functional groups (Matsuura et al., 1991). Many chemists have introduced CF3 in polyimides backbone either by means of diamine or dianhydride unit to overcome the solubility issues (Zhao et al., 2008; Jiang et al., 2008). Continuing our investigations in this important area (Nawaz et al., 2008), we have prepared the title compound, (I), which is also a monomer diamine containing two CF3 groups incorporated to enhance the solubility of the resulting polyimides.

The structure of the title compound is presented in Fig. 1. Its bond lenghts and bond angles agree with the corresponding bond lengths and bond angles reported for closely related structures (Nawaz et al., 2008; Bocelli & Cantoni, 1989. The crystal structure of the title compound is stabilized by N—H···O and N—H···F hydrogen bonds; details have been provided in Table 1.

Experimental

4,4'-(Perfluoropropane-2,2-diyl)bis((4-nitrophenoxy)benzene) (2.00 g, 3.98 mmol) was reduced to corresponding diamine using 10 mL hydrazine and 0.10 g Pd—C as catalyst in 80 mL ethanol under reflux for 24 h. The reaction mixture was filtered and solvent was evaporated to obtain the crude product. It was later recrystallized from absolute ethanol. (Yield 1.56 g; 76%, m.p = 428 (2) K).

Refinement

In the absence of anomalous scatterers, Friedel pairs (1848) were merged prior to refinement. All H atoms could be located by difference Fourier synthesis. Those bonded to C were refined with fixed individual displacement parameters [U(H) = 1.2 Ueq(C)] using a riding model with C—H = 0.95 Å. The H atoms bonded to N were refined isotropically.

Special details

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 &gt; 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.
