(3Z)-1,1,1-Trifluoro-4-phenyl-4-[(2-{[(1Z)-4,4,4-trifluoro-3-oxo-1-phenyl­but-1-en-1-yl]amino}­eth­yl)amino]­but-3-en-2-one

In the title compound, C(22)H(18)F(6)N(2)O(2), 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 –CF(3) groups are disordered over three sets of sites with site-occupation factors of 0.318 (4), 0.360 (10) and 0.322 (9).
