Description
The structure of deuterated formic acid has been refined using neutron powder diffraction data collected at 4.5 (+- 1.) K, with isotropic and anisotropic temperature factors. The resulting geometry is compared with that from a previous X-ray determination [Holzberg, Post and Fankuchen, Acta Cryst. (1953), 6, 127-130]. In the present refinement the C-O bond lengths are different [1.36 (2), 1.23 (2) A] and are in agreement with those of other carboxylic acids. The presence of deuterium causes an increase in the O...O bond length. (Auth.)
