Known structure

Dear Editor

In the latest IUCr Newsletter (vol. 11. No 1, p.7) you reported on the article in Acta Cryst, E59 (2003) describing the structure of trichloroacetic acid.

Maybe it is worth noting that neutron diffraction structure of this crystal has been known since 1972 at least (P.-G. Jonsson, W. C. Hamilton, J. Chem. Phys., 56, 4433 (1972)).
