1,4-Bis(fluoro-meth-yl)benzene

Abstract

The title compound, C8H8F2, lies across a crystallographic inversion centre. The structure features short C⋯F [2.8515 (18) Å] and F⋯F [2.490 (4) Å] contacts, which are significantly shorter than the sum of the van der Waals radii of these atoms. The F atom and methyl-ene H atoms are disordered over two positions with a site-occupancy ratio of 0.633 (3):0.367 (3). In the crystal structure, inter-molecular C - H⋯F inter-actions link neighboring mol-ecules into infinite chains along the b axis. In addition, C - H⋯π inter-actions link these mol-ecules along [10 ], forming a two-dimensional network parallel to (101).
