F contacts (in the range 2.45-2.73 Å) between molecules. The short contacts are associated with the disorder. The dihedral angle between thiophene rings is 57.44 (8)°. The 5-(4-cyanophenyl)-3-methyl-2-thienyl groups of adjacent molecules are parallel, leading to zigzag chains of molecules along [101]. The dihedral angles between each thiophene ring and its adjacent cyanobenzene ring are 8.9 (2) and 7.15 (10)°. Supporting information

H atoms were positioned geometrically and refined using a riding model with Uiso(H) = 1.2 times Ueq for the associated atom (1.5 times for methyl groups with free rotation about the C—C bond). The perfluorocyclopentene ring is disordered with two components. Refinement of the disorder was performed using PART 1, PART 2 and FVAR in SHELX. The minor component was restrained using the SAME instruction in SHELX to give similar bond distances and angles as the major component. Related atoms and atoms in close proximity were refined with identical or similar displacement parameters using either EADP or SIMU instructions in SHELX. The chloroform site is also disordered and contains half of the molecules with two unique components close to a symmetry element. The geometry of the major component of disordered chloform was restrained and the second component was constrained to the same geometry.
During research focused on new synthetic routes towards novel substituted thienylperfluorocyclopentene, we have synthesized and purified the title compound (I). The crystal structure of I contains disordered chloroform solvent located close to a two-fold axis. The perfluorocyclopentene ring is disordered with two components having 68.5 (3)% and 31.5 (3)% occupancy related by a flip between alternative envelope configurations (Figure 2). Unfavourably close F···F contacts with distances in the range 2.45–2.73 Å between pairs of molecules may partly account for the disorder in the ring. The planes of both 5-(4-cyanophenyl)-3-methyl-2-thienyl groups of the molecule are parallel with similar groups of neighbouring molecules, with interplanar distances of 3.39 Å and 3.50 Å, forming zigzag chains parallel to the [101] direction (Figure 2). Stacking of the chains forms planes parallel to the (101) plane.

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

During research focused on new synthetic routes towards novel substituted thienylperfluorocyclopentene, we have synthesized and purified the title compound (I). The crystal structure of I contains disordered chloroform solvent located close to a two-fold axis. The perfluorocyclopentene ring is disordered with two components having 68.5 (3)% and 31.5 (3)% occupancy related by a flip between alternative envelope configurations (Figure 2). Unfavourably close F···F contacts with distances in the range 2.45–2.73 Å between pairs of molecules may partly account for the disorder in the ring. The planes of both 5-(4-cyanophenyl)-3-methyl-2-thienyl groups of the molecule are parallel with similar groups of neighbouring molecules, with interplanar distances of 3.39 Å and 3.50 Å, forming zigzag chains parallel to the [101] direction (Figure 2). Stacking of the chains forms planes parallel to the (101) plane.
