2,3,4,5,6-Penta-fluoro-trans-cinnamic acid.

ABSTRACT: The title compound, C9H3F5O2, crystallizes as O-H?O hydrogen-bonded carb-oxy-lic acid dimers that, together with C-H?F inter-actions and O?F [2.8065?(13) and 2.9628?(13)?Å] and F?F [2.6665?(11), 2.7049?(12) and 2.7314?(12)?Å] contacts, form a sheet-like structure. The sheets are stacked via short ?-? inter-actions [centroid-centroid distance = 4.3198?(11)?Å]. An intra-molecular C-H?F inter-action is also observed.

The title compound, C9H3F5O2, crystallizes as O-H⋯O hydrogen-bonded carb-oxy-lic acid dimers that, together with C-H⋯F inter-actions and O⋯F [2.8065 (13) and 2.9628 (13) Å] and F⋯F [2.6665 (11), 2.7049 (12) and 2.7314 (12) Å] contacts, form a sheet-like structure. The sheets are stacked via short π-π inter-actions [centroid-centroid distance = 4.3198 (11) Å]. An intra-molecular C-H⋯F inter-action is also observed. ...[more]
