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

ABSTRACT: The title compound, C(8)H(8)F(2), 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?? inter-actions link these mol-ecules along [10], forming a two-dimensional network parallel to (101).

The title compound, C(8)H(8)F(2), 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.  ...[more]
