In the title compound, C22H18F6N2O2, the five atoms comprising each O=C—C=C—N fragment are almost coplanar (the r.m.s. deviation for the fitted atoms being 0.008 and 0.002 Å) and form a dihedral angle of 47.70 (12)°. The phenyl ring attached to each of the O=C—C=C—N fragments is twisted out of the respective plane with dihedral angles of 64.46 (11) and 61.82 (10)°, respectively. An almost orthogonal relationship for the phenyl rings is indicated by the dihedral angle between them of 78.19 (14)°. The conformation about each ethylene bond is Z, which allows for the formation of intramolecular N—H⋯O hydrogen bonds which close S(6) loops. The most prominent feature of the crystal packing are N—H⋯O hydrogen bonds that result in supramolecular chains along the a axis. The F atoms of one –CF3 groups are disordered over three sets of sites with site-occupation factors of 0.318 (4), 0.360 (10) and 0.322 (9).

A mixture of the N,N'-bis(1-ethylidene)ethane-1,2-diamine (0.01 M) in THF (30 ml) and trifluroacetic anhydride (0.025 M) was refluxed for 2 h. The solid which separated on cooling was recrystallized from ethanol. M. pt: 477–478 K. Yield: 70%.
Carbon-bound H-atoms were placed in calculated positions [C—H = 0.95–0.99 Å, Uiso(H) = 1.2Ueq(C)] and were included in the
in the riding model approximation. The N-bound H-atoms were located in a difference were refined freely. One trifluoromethyl group is disordered over three positions in respect to the F atoms. The C—F distances were restrained to within 1.35±0.01 Å, and the F···F distances to 2.21±0.01 Å. The disordered F atoms were refined isotropically and the final site occupancies were 0.318 (4), 0.360 (10) and 0.322 (9) for the unprimed, primed and doubly primed atoms, respectively.Recently, some of us described the structure of the 2-thienyl derivative (Asiri et al., 2011) of the title compound, (I). Herein, the crystal and molecular structure of (I) is described which has –CF3 groups rather than thienyl substituents.
In (I), Fig. 1, the five atoms comprising each O═C—C═C—N fragment are co-planar with the r.m.s. deviation for the fitted atoms being 0.008 Å [for the plane containing the O1 atom] and 0.002 Å [O2]; the dihedral angle between the planes is 47.70 (12)°. The conformation about each ethylene bond is Z allowing for the formation of intramolecular N—H···O hydrogen bonds which close S(6) loops, Table 1; a similar conformation and S(6) loops were observed in the two independent molecules of the 2-thienyl derivative (Asiri et al., 2011). The attached phenyl ring is twisted out of the plane through the O═C—C═C—N fragment, forming dihedral angles of 64.46 (11) and 61.82 (10)°, respectively; the dihedral angle between the phenyl rings is 78.19 (14)°.
The crystal packing also features N—H···O hydrogen bonds so that each amine-H and each carbonyl-O atom is bifurcated, Table 1. The result is the formation of four-membered {···H···O}2 synthons and supramolecular chains along the a axis, Fig. 2.

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, some of us described the structure of the 2-thienyl derivative (Asiri et al., 2011) of the title compound, (I). Herein, the crystal and molecular structure of (I) is described which has –CF3 groups rather than thienyl substituents.
In (I), Fig. 1, the five atoms comprising each O═C—C═C—N fragment are co-planar with the r.m.s. deviation for the fitted atoms being 0.008 Å [for the plane containing the O1 atom] and 0.002 Å [O2]; the dihedral angle between the planes is 47.70 (12)°. The conformation about each ethylene bond is Z allowing for the formation of intramolecular N—H···O hydrogen bonds which close S(6) loops, Table 1; a similar conformation and S(6) loops were observed in the two independent molecules of the 2-thienyl derivative (Asiri et al., 2011). The attached phenyl ring is twisted out of the plane through the O═C—C═C—N fragment, forming dihedral angles of 64.46 (11) and 61.82 (10)°, respectively; the dihedral angle between the phenyl rings is 78.19 (14)°.
The crystal packing also features N—H···O hydrogen bonds so that each amine-H and each carbonyl-O atom is bifurcated, Table 1. The result is the formation of four-membered {···H···O}2 synthons and supramolecular chains along the a axis, Fig. 2.
