چکیده
In the title compound, C16H8F6N2, the dihedral angle between the pyrazole and di-fluoro-benzene rings is 50.30 (13)°, while those between the pyrazole and fluoro-benzene rings and between the di-fluoro-benzene and fluoro-benzene rings are 38.56 (13) and 53.50 (11)°, respectively. Aromatic π-π stacking inter-actions between adjacent di-fluoro-benzene rings [centroid-centroid separation = 3.6082 (11) Å] link the mol-ecules into dimers parallel to [21-2].

The title co-crystal, 3-(4-fluoro-phen-yl)-1H-pyrazole-5-(4-fluoro-phen-yl)-1H-pyrazole (1/1), C9H7FN2, crystallizes with four independent mol-ecules (A, B, C and D) in the asymmetric unit exhibiting two tautomeric forms (A and D; B and C) due to N-H proton exchange between the two N atoms of the pyrazole ring. The dihedral angles between the mean planes of the pyrazole and benzene rings are 15...
